Salem's Lot Review: Stephen King's Iconic Vampire Tale Gets a Chilling but Small Film

The Sleep Experiment is an excellent horror film that dives deep into the psychological damage caused by a top-secret government experiment. Based on Creepypasta’s The Russian Sleep Experiment , writer/director John Farrelly delivers his first feature film that exposes the horrors of what humanity is capable of when pushed to the brink. The film begins with a slow burn, however, as time passes on and the test subjects begin to hallucinate, the plot transitions into the psychological thriller realm before escalating into full physical horror in the final act. The Sleep Experiment has some pretty decent twists and turns along the way (some more obvious than others), but overall has a very solid story with a great performance from the entire cast.

Spoiler Warning Two detectives David (Anthony Murphy) and Robert (Barry John Kinsella) begin an investigation on the ethics involved in the top-secret research facility, Porton Down. One experiment stands out to them as the most horrific, The Sleep Experiment, a scientific experiment that took place during the Cold War. The experiment consisted of five prisoners, deemed Enemies of the State, being locked in a sealed gas chamber. An airborne stimulant was continually administered to keep the subjects awake for 30 consecutive days. The prisoners were promised that they would be set free and erase their prison sentences if they successfully complete the experiment.

In the film’s opening scene, a vehicle is driving through the night on May 16th, 1961, and arrives at a secret facility. Armed guards wearing protective gear wait outside the building as five hooded men are escorted down a dark staircase into an underground bunker. The five men are all prisoners held on national security charges, Luke (Will Murphy), Patrick (Sam McGovern), Edward (Rob James Capel), Sean (Brian Moore), and Eric (Steven Jess). Fifteen years in the future, the two detectives are interviewing Christopher (Tom Kerrisk), about his involvement with the experiment.

As the experiment officially begins, the five prisoners begin to become better acquainted with each other. They each introduce themselves and reveal their backstories as well as why they were originally sent to prison before participating in the experiment. The prisoners were all charged and convicted with either murder or attempted murder. The men are hopeful that they will successfully complete the experiment so that they can be released from prison and return home to their families. Back in 1976, the two detectives believe that Christopher was the person who designed the sleep experiment for the military.

As the interview continues, Christopher reveals that the five prisoners weren’t randomly chosen for the experiment, but in fact, they each volunteered to participate. The detectives accuse Christopher of being responsible for the deaths of nine people when the experiment was being conducted. On the fourth day of the experiment, Eric begins to struggle mentally while Patrick has an asthma attack. The guards enter the room and escort Patrick to receive medical attention. The very next day (Day 5), Patrick returns to the experiment room where the rest of the prisoners immediately become suspicious of his actual whereabouts.

Hallucinations Rapidly Approach

As the film’s timeline continues to shift back and forth between 1961 and 1976, Christopher provides plenty of details and information to the two detectives about his design. During the interview, Christopher discovers that the experiment is connected personally to Robert, learning that his father was one of the test subjects. On Day 12, Patrick has another asthma attack and is escorted out of the room for the second time. The men begin having extreme hallucinations as Eric and Sean scream and demand to be released from the experiment. The next day, Patrick returns to the experiment room where he doesn’t seem to be in the same condition as his fellow test subjects.

Luke becomes even more suspicious of Patrick only to learn that he has been taking notes of everything that has happened for the past twelve days. Edward experiences a severe hallucination where he believes that Luke is responsible for the death of his daughter. As Edward confronts Luke, Luke unveils the notebook that he had stolen from Patrick. It is revealed that Patrick was an undercover test subject the entire time. Luke provokes Edward into believing that he truly killed his daughter until Edward reaches a mental breaking point and brutally kills Luke.

With Luke dead and the other test subjects mentally spiraling out of control, on Day 14, the scientists decide to shut down the experiment and immediately send armed guards into the room. As the guards cautiously enter the pitch-dark room, they are violently attacked by the prisoners, causing more deaths in the process. The surviving guards are able to successfully remove the prisoners from the room where they immediately seek medical assistance. Back in 1976, Christopher leaves the interview before apologizing to Robert about his father.

After the interview, the detectives decide to continue their investigation where they speak with a chemical engineer who helped conduct the experiment. They discover that Christopher not only designed the experiment but was also the lead scientist. David races to Christopher’s home only to find that he had already left town. In the basement of Christopher’s home, David finds and listens to a tape recording only to learn the horrible truth of Christopher's intentions and the end result of the five prisoners.

John Farrelly Succeeds in Filmmaking

From the directing standpoint, John Farrelly did not disappoint with The Sleep Experiment . Both timelines in the story transitioned at a very good pace, while the cinematography and soundtrack are superb. With only an hour and 20-minute runtime, the film did seem short, but it gets straight to the point and doesn’t prolong the story whatsoever. The Irish psychological thriller , The Sleep Experiment , is a film worth watching and certainly payoffs as an outstanding first feature film for John Farrelly.

The Sleep Experiment comes to us from Red Water Entertainment and is currently available on a number of digital and cable platforms, including iTunes, Amazon, Google Play, iNDemand, and DISH.

The sleep experiment.

Reviewed by: Jennie Kermode

The thing about the experiments carried out at Porton Down in the mid 20th Century – which followed, to an extent, in the same tradition as MK Ultra in the US – is that so much remains hidden about them, and there is so much denial surrounding them, that fiction writers can use them as a foundation for all sorts of things. Writer/director John Farrelly has claimed them as inspiration for this thriller about prisoners and sleep deprivation, but it has notable features in common with a similarly titled Creepypasta story. What gives it some weight regardless is its focus on Irish characters, which reflects other aspects of the troubled history of the British state and makes the central premise all too believable.

This concerns five men, hooded and marched into what looks like an underground bunker in the opening scenes. All serving lengthy prison sentences, they have been told that they will have them commuted if they cooperate in an experiment which involves an experimental gas. “You must stay awake for the next 30 days. You must complete all physical activities. You must obey any orders given to you without delay. Strictly no physical contact between each other,” intones a voice. The parameters of the experiment are clumsily drawn. It doesn’t seem likely to produce good quality data, but its flaws are in line with the approach of similar studies at the time, and there’s no reason to assume somebody would have intervened.

We watch events unfold at a distance, the idea being that events in the bunker were recorded on tapes and are being reviewed by detectives many years later. Farrelly’s shooting style doesn’t fit this narrative, so you will have to suspend disbelief, but the format enables him to jump back and forth, introducing new snippets of information wherever they are most effective from a dramatic perspective. One tape is missing, and yes, it does turn up right at the end. In the meantime, the detectives build on their observations from the tapes by interviewing psychologist Christopher Sampson (Tom Kerrisk), who designed the experiment.

Down there in the bunker in the past timeline are likeable, practical Edward (Rob James Capel), who is sympathetically presented as having committed murder only to avenge his murdered child; shy young Eric (Steven Jess), who immediately triggers Edward’s protective instincts; pushy but personable Sean (Brian Moore); tediously vacant psychopath Luke (Will Murphy); and peculiarly well-adjusted Patrick (Sam McGovern), who just wants to get it all over with and get out, but who may have a secret. Viewers will immediately suspect that these particular characters have been placed together for a reason which goes beyond what they’ve been told about, and indeed, they don’t need sleep deprivation to start getting on each other’s nerves. Knowing this, Farrelly reveals early on that something went horribly wrong, and has the detectives demand to know more about the men’s backgrounds and why they were chosen.

There’s a lot of potential here, and the result is a film which, whilst disastrous in some respects, works well in others. Let’s get the bad stuff out of the way first. Kerrisk’s acting, on which key aspects of the film depend, is terrible. The dialogue is pretty bad throughout, but where other actors mostly succeed in pulling it off, he’s hopeless, trotting out a bizarre description of what it means to be a psychopath as if reading from a Fifties textbook, contributing to the predictable and flaccid ‘twist’ ending in a style which recalls the Republic serial villains of the 1930s, totally at odds with the rest of the film. This is particularly frustrating because not only does it let down the good work elsewhere, it also risks making the whole thing so comical as to provide cover for real life equivalents.

By contrast, the drama in the bunker is quite well handled, with solid work from most of the actors, especially in the early stages. The film is at its strongest before it starts obliging them to show the effects of mental disintegration, but even then, some of it is quite effective, with Eric getting overwhelmed early on due to difficulty in filtering noise, something which many viewers will have experienced for themselves when under stress. Capel and Moore work well together and will leave you wanting to see more of the prisoners’ experience. There’s enough here to illustrate that Farrelly is not without talent. It’s just a shame that the cheesy, clumsily handled aspects of the film prevent it from achieving its potential.

The Sleep Experiment

By Chris Esper | March 9, 2023

According to an urban legend, in 1947, in Soviet Russia, an experiment was conducted in which five prisoners were promised freedom if they could stay awake for 30 consecutive days in a chamber. This would be administered using a gas stimulant. The prisoners were chosen based on their being considered an enemy of the state. However, the experiment was a failure, resulting in multiple deaths. That is the basis for writer-director John Farrelly’s horror/thriller debut,  The Sleep Experiment .

In 1961, prisoners Edward (Rob James Capel), Sean (Brian Moore), Luke (Will Murphy), Eric (Steven Jess), and Patrick (Sam McGovern) volunteered to stay up for a month straight. The experiment is being conducted by scientist Christopher Sampson (Tom Kerrisk), who works for Porton Down, a science park in England. Edward is a hulking presence charged with murder after attempting to avenge his daughter’s death. Thief Sean wants to see his aunt again after losing his mother. Luke killed children. Eric is unassuming and looks innocent, though he’s serving a sentence for murder. Patrick is the most mysterious of them all but is also the most stable.

Meanwhile, in 1976, two cops, David (Anthony Murphy) and Robert (Barry John Kinsella), are investigating Christopher and the experiment. The investigation is intercut with the prisoners in the gas chamber, showing the events that occur while counting down the days. The story is presented in five chapters, showing each prisoner’s slowly decaying mental state. The results are bloody, violent, and revealing in their conclusion.

“… five prisoners were promised freedom if they could stay awake for 30 consecutive days…”

Farrelly, at just the ripe age of twenty-two, shot  The Sleep Experiment  for 25 days stretched over four years. As a debut, it is impressive on a technical level. The opening scenes feature nicely crafted shots as photographed by Alice Hollingsworth. One of the highlights includes when the prisoners first arrive in the chamber, hooded, and the experiment’s rules are explained. During this speech, the camera moves 360 degrees around the room, showing how little there is. It’s also foreshadowing what is coming. Unfortunately, this kind of promise disappears shortly after the first half hour. 

The premise on its own is excellent and is genuinely interesting at its start. That said, the film has a bad habit of over-explaining. There is so much dialogue between Edward, Sean, Luke, Eric, and Patrick as they recount the reasons for their arrest. While there are flashes of imagery showing the prisoners at the scene of their crimes, it is not enough. Worse still, the overpowering music makes it hard to discern what anyone says.

The conclusion, while genuinely creepy, featured a lot of expository dialogue, which is not only hard to understand but also underwhelming. The investigation scenes also come off as problematic. For example, one of the cops, as it turns out, has a personal connection to one of the prisoners. However, this is never mentioned again for the remainder of the runtime nor revealed which prisoner it is. Understanding this character and connection would have created more investment.

For everything there is to like in  The Sleep Experiment , there is something not to like. Some of the twists and turns are well executed, while others are not. Farrelly has a clear vision as a filmmaker and directs his cast well. He and Hollingsworth also make the visuals quite nice. However, the film falters in its writing and storytelling, leaving little surprise as it concludes. Still, Farrelly is a filmmaker to watch as he develops his cinematic voice.

Spoiler-Free Judgment Zone

Just think how much you could get accomplished if you didn’t need to sleep. Sounds great doesn’t it? Well, this unfolds showing that it’s not a good thing at all. It’s a good film though, other than a music soundtrack that was a little overbearing at times. It’s interesting watching as things fall apart more and more.

It’s 1961. A bunch of guys are on a truck with burlap sacks over their heads. They’re led downstairs into the basement of the place and hosed off. They’re clearly prisoners, and they are led into a room. A voice comes over the loudspeaker for them to remove their sacks. These five men have been accepted into the sleep experiment. All charges against them will be dropped if they follow the rules:

• They must stay awake for the next 30 days
• They must do physical activities when instructed
• They must obey all orders
• There will be no physical contact with each other.
• There will be an experimental gas administered to help keep them from falling asleep.

Credits roll.

Chapter One: The Investigation

Two policemen go to see Christopher about the top-secret documents that were leaked to the papers. They put him in the interrogation room and ask him about the sleep experiment from fifteen years ago. Why did it go so wrong? The police seem to imply that one of the prisoners was a serial killer or psychopath. According to reports, Christopher is the one who designed the project.

On day 1, the men get used to the room they’ll be in. Eric is one of the prisoners; he’s there for murder, and the others lie about why they’re there.

On Day 2, the men talk more about their backgrounds, and Luke and Sean argue with each other. Each of the men then has to do some physical workouts, in order, one at a time. Luke is a bit odd, Sean is a jerk, Eric is the quiet one, Patrick doesn’t have much to say either, and Edward is the older, bald man.

On day 3, they share more personal details with each other.

On day 4, the men start showing signs of sleep deprivation. The gas they’ve been breathing doesn’t remove the need for sleep, it just doesn’t let them sleep. Eric complains about the loud eating and breathing of the others. Patrick has some kind of seizure, and he’s removed by the guards.

Chapter Two: The Impostor

Patrick is returned to the group. He had a reaction to the gas because of his asthma. Luke seems to know a lot about medicine and asthma.

Back in the interrogation room, Christopher thinks one of the police officer’s fathers was involved with the experiment.

On Day 5, Luke admits that he’s killed people. They talk about justified murder. Luke tells his story about killing a little girl, and Edward gets ready to kill him before the guards intervene.

We get a flashback where Patrick is told to fake an asthma attack on certain days. He’ll be allowed to sleep during those times.

Chapter Three: The Diary

Christopher explains that by day twelve they all had experienced extreme hallucinations. Patrick has another seizure and is once again removed from the room. Eric continues to write in his diary. Eric freaks out and vomits blood on the door. Sean hears his mother’s voice. She comes to him with a noose around her neck; she killed herself because he left her. We see that Luke switches books with Patrick’s diary and reads it.

Day 13, Patrick is returned to the group again, but he doesn’t seem as messed up as the others. Are they letting him sleep outside? Luke knows that Patrick is a fake.

Chapter Four: The Yellow School Bag

Edward hugs his daughter, and he notices her yellow school bag. That bag ties in with Luke’s story about killing the girl. Luke basically admits it and then spills the beans about Patrick and his diary as a distraction. Edward threatens to kill Luke someday, but he won’t do it now, because he wants the promised pardon. Luke doesn’t let it go, so Edward kills Luke with a toilet lid. Edward then covers the see-through mirrors with blood, which blinds the scientists.

On Day 14, the researchers flood the room with sleeping gas and go in to rescue Patrick. Edward then turns on the researchers and tears them apart.

Back at the police station, Christopher winds up his story and goes home.

Chapter Five: The Missing Tape

Robert and David, the two policemen, continue their investigation. One woman talks about some atrocities in a different experiment, and she mentions that Christopher had designed more than just that one experiment…

David goes back to Christopher’s house that night and finds a room in the basement that contains a tape; the one missing tape from the experiment.

Day 24, and Edward is the only subject remaining. Christopher asks Edward if he feels guilty after killing Luke and the two soldiers. “Alive,” Edward replies. Edward wants to know if Luke really killed his daughter, and Christopher explains that he didn’t.

Christopher admits to Edward that he’s a psychopath with no qualms about killing at all. He took this job, designing experiments that would always go wrong so he could kill people without being discovered.

Turns out there was a psychopath involved in the experiment– Christopher, the lead researcher.

This is based on a more-or-less true story– no, not really. The original story was a “ creepypasta ” that became immensely popular. There was never a real Russian Sleep Experiment. The original story had monsters, and this one didn’t.

The music is a little too loud, and it makes some of the dialog hard to understand at points, especially Sean, who has a pretty thick Irish accent.

It’s definitely creepy, but not supernatural in any way; it’s just a bunch of people with madness lying just below the surface. The acting is fine, except maybe for Christopher, who is a little over-the-top evil, especially at the end. The cinematography and directing were good; the main set was appropriate, the sound was good, except for the too-loud background music at times.

Overall, we liked it.

Wide Awake After This Irish Horror | The Sleep Experiment Review

In lieu of their prison sentences, five men agree to be participants in top-secret experiment in which they will be prevented from sleeping for thirty days. Two detectives are tasked with interviewing the researchers involved in the subsequent events in which the experiment went catastrophically wrong, leading to death and destruction. Weaving these related plots together, The Sleep Experiment is a captivating and frequently horrifying narrative of revelation from first-time Irish director John Farrelly.

Adapted from Russia in the 1940s to Ireland in Cold War era 1961, the film’s script is based on the popular Creepypasta myth the Russian Sleep Experiment, with the basic premise expanded to explore the inner psyches of many of the key players, as well as added arcs, twists and turns. And while evident from its source material that The Sleep Experiment is unabashedly a horror, there are also clear dramatic influences. Its focus on monologue, which characterises the both the detectives’ interviews and the prisoners’ revelations on their pasts, gives the film a the pervading theme of confession, lending the production a particularly Irish flair.

Writer, director and editor Farrelly worked on The Sleep Experiment during his final year of secondary school in 2018, not long after winning Young Filmmaker of the Year at the Limerick Fresh Film Festival. Adding to his undeniably impressive set-up is a strong cast of Irish actors, each tasked with the difficult job of playing layered characters presenting heavily edited versions of themselves in a heavy atmosphere of paranoia – much of which is not just in their heads.

Set primarily in tight, claustrophobic locations, The Sleep Experiment ’s cinematography impressively adds to the film’s overall sense of dread. The production makes impressive use of the prisoners’ Spartan bunker setting, with the camera work keeping the action alive and compelling. The lighting is employed strongly throughout to create jarringly intimate scenes at one moment and horror-filled instances of the uncanny in the next. There are also some disturbing moments of gore and violence, but much of the film’s horror is also delivered via the actors’ speech and the implication of what we don’t see.

Seeing what can be achieved here by a young director and a dedicated cast and crew, The Sleep Experiment has already a considerable success for Irish cinema: following a packed premiere on the 27 th of October it has been released on several streaming platforms including Amazon Prime and Apple TV. With strong performances, a haunting aesthetic and a compelling and ever-evolving plot, The Sleep Experiment is very much worth watching.

The Sleep Experiment is currently available to stream online.

Review: The Sleep Experiment

Written and directed by John Farrelly , two detectives begin an investigation into a disastrous secret military experiment where five prisoners were kept awake for thirty days in a sealed gas chamber. Starring: Rob James Capel , Will Murphy , Tom Kerrisk , Barry John Kinsella and Will Murphy .

It’s horrific to imagine the sorts of traumatic experiments governments and scientists got away with in a time with so much less transparency and culpability, so it’s not surprising that The Sleep Experiment was inspired by real events. The concept is a good one but it’s massively undercut by the style of the film. Where we should be getting a growingly disturbing atmosphere, it all feels very false and synthetic. It’s a harsh, twisted story but that isn’t translating into the aesthetic or tone, there’s a stage-like presence to it, it’s too cleanly put together.

That lack of individual style fights against the intrigue of its story, making it work too hard when it should speak for itself. You don’t have to be an expert to know what lack of sleep does to the psyche so that alone gives the film oodles of complicated, violent and hysterical potential. In some ways it does capitalise on that but it’s also being used to set up a secondary story, exploring those being investigated for the experiment. That split means neither really get the space that they need to make for a satisfying punch, instead leaving it feeling far too open, needing to follow the road further.

Its insincere quality unfortunately is only further fed by its actors, in particular Tom Kerrisk ’s overly stereotypical English accent. He brings a cliched presence, not able to dive into the complexities of the character, which negatively impacts the progression of the story. The performances in general feel too by the book, they’re ticking the boxes but not giving anything unique or gripping. What they are bringing to the table makes this story all the more obvious, so the mysterious or complex potential goes mostly unanswered.

The Sleep Experiment tries to explore cruelty and crime but can’t capitalise on the mayhem and chaos that naturally arise. It misses out on a real or sincere note, everything feels overly composed and structured, which undermines the tone and atmosphere needed to drive home this story. It’s the same case for most of the cast and it sadly just falls into too many stereotypes for this to work. It’s disappointing as there’s a decent crime story at its foundation, with a potentially complex antagonist but neither are done justice.

Verdict: ✯✯ | 4/10

Sleep Korean Movie Ending Explained: What Happens In The Mystery Thriller?

As the night passes, soo-jin worries more and more about her husband's behavior..

Sleep (Credit: Roku)

In his first feature film, Sleep is a 2023 South Korean black comedy horror mystery thriller that Jason Yu wrote and directed. Before its September 6, 2023 release in South Korea, the picture, which stars Jung Yu-mi and Lee Sun-Kyun, made its world premiere on May 21, 2023, at the Critics’ Week portion of the Cannes Picture Festival.

The protagonists of the tale are Soo-jin and Hyun-su, an expectant couple coping with anxiety and terrifying dreams of sleepwalking. The movie takes a terrifying turn as Hyun-su’s sleepwalking gets worse and involves eating raw meat and other unsettling behaviours.

Following the discovery of Hyun-su’s REM sleep condition through a sleep study, the pair makes humorous attempts to address the problem. The story takes a turn towards a paranoid possession thriller with a ticking clock when a shaman is introduced, implying a supernatural element.

At ninety-five minutes, Sleep is a distinctive film that delves into the couple’s tenacity in the face of otherworldly obstacles. It’s safe to say that SLEEP will make viewers think beyond the box. Upon finishing the film, there is a persistent urge to rewatch it to verify specific scenes or dispel any remaining doubts.

Prepare yourself for a rollercoaster journey of feelings, ranging from shock to incredulity to horror. There is a lot to process, and viewers may leave the movie feeling disoriented and depleted.

Soo Jin is expertly portrayed by Jung Yu Mi, who displays a wide range of emotions that help viewers relate to her predicament. However, Lee Sun Kyun confronts Hyun Su’s character head-on and, in his unique way, shows his wife how much he loves her throughout the entire film.

Plot Of The Movie

In the 2023 South Korean film “Sleep,” newlyweds Hyeon-soo and Soo-jin’s story is told. Their tranquil existence takes an unsettling turn when Soo-jin learns that Hyeon-soo exhibits strange behaviour and sleepwalking. As the night passes, Soo-jin worries more and more about her husband’s behaviour, especially because she fears for their infant.

Why the Horrors of the 'Russian Sleep Experiment' Probably Didn't Happen

This animation investigates the facts behind this pervasive urban myth.

Especially if you haven't been getting a lot of sleep lately, you might wonder just how long you can go on like that. Exactly how long could you stay awake without cracking as a result of sleep deprivation? Some people say there was an over-the-top experiment for that. Experts are quick to debunk it.

The Russian Sleep Experiment is a popular urban myth which began to circulate online in "creepypasta" forums (so-named for the ease with which you could copy-paste spooky content) in the early 2010s. But could this deeply unsettling legend have had some roots in fact?

The story goes that Soviet-era scientists created a stimulant which they believed would enable soldiers to not require sleep for up to 30 days. They decided to test their new gas on five prisoners, promising them their freedom upon completion of the experiment. They locked the five men in a hermetically sealed chamber and began pumping in the gas. Within a few days, the men were exhibiting the kind of paranoia and psychosis that is a typical symptom of sleep deprivation. But as time went on, they began to act even more strangely.

15 days into the experiment, when scientists could no longer see the men through the thick glass of the chamber, or hear them through the microphones, they filled the room with fresh air and unlocked it. There, they discovered that one of the men was dead, and the four surviving test subjects were all sporting horrendously violent injuries, some of which appeared to be self-inflicted.

Attempts to sedate the men were either unsuccessful, or led to their deaths the moment they lost consciousness. Finally, when one of the researchers asked what exactly these men had become, the last surviving test subject told him that they represented the potential for evil that exists in all human beings, which is usually contained by sleep, but had been unleashed by their constant wakefulness. Chilling stuff.

Is any of the Russian Sleep Experiment actually true?

According to a video from The Infographics Channel on YouTube, which provides animated summaries of events from history, current events and literature, the Russian sleep experiment almost certainly has its basis in fiction. For one thing, there's the fact that the story's sole original source seems to be a website dedicated to telling creepy (made-up) stories. But even the science doesn't hold up.

Experts are quick to refute this myth as well. There's no scientific ground proving that gas (or any other substance, for that matter) can keep a person awake for 30 days, says Po-Chang Hsu, MD , an internal medicine physician and medical content expert at SleepingOcean. “Some drugs and high caffeine dosages may grant a couple of days without shut-eye, but 30 is impossible,” he says.

Additionally, this experiment is unlikely because of the effect sleep deprivation has on the brain, Dr. Hsu says.

“Even after a few days, a person can start hallucinating, which would make it extremely hard for them to perform simple daily actions, let alone deal with military assignments that require extreme focus,” he says.

So how long can someone truly stay awake?

The current documented world record for staying awake is a bit longer than 11 days , which was achieved by Randy Gardner in 1963. Gardner experienced severe behavioral and cognitive changes during those 11 days (even though he wanted to prove that nothing bad would happen when a person doesn’t sleep), Dr. Hsu says. He also experienced mood swings, memory issues, severe difficulty focusing, paranoia and hallucinations.

While there is some truth to the claims that amphetamines have been used to keep soldiers alert in historical times of war, there is no scientific evidence of a gas existing that could keep anyone awake for 15 days. And studies have found that after just 48 hours without sleep, people tend to become slower, disoriented, prone to making mistakes, and ultimately less effective as a soldier.

“Since the brain can’t function properly after being sleep-deprived for 11 days, it’s safe to assume things would get much worse if one tries to stay awake longer,” he says. “Consequently, those soldiers would’ve been useless even if they miraculously managed not to sleep for 30 days.”

Still, whoever came up with the story of the Russian sleep experiment in the first place deserves points for their creative writing... if not for medical accuracy.

At any given moment, the Korean psychological chiller “Sleep” could have easily switched gears and become a lame horror comedy. Instead, it’s a fine-tuned (and eerie) marital drama where one partner suffers from a bad case of sleepwalking while the other worries about it, so it’s both a paranoid thriller and a slow-burning ghost story. In his impressive debut feature, writer/director Jason Yu strikes a fine balance between character-driven and high-concept horror. It helps that co-leads Jung Yu-mi and the late Lee Sun-kyun have great on-screen chemistry as a weary but well-attached couple. But “Sleep” still treads such a fine line in its depiction of a relationship in crisis that it takes a moment for Yu’s quick, sure footing to register as his movie’s greatest asset. 

Neither sudsy nor conventional, “Sleep” moves briskly with its characters as they try to unravel what may or may not be a spooky mystery. First, Hyun-su (Lee) wakes up from a dead sleep. “Someone’s inside,” he murmurs. Neither Hyun-su nor his pregnant wife, Soo-jin (Jung), can determine what that means. He thinks they can track, diagnose, and quarantine their new problem like a project that can be chipped away through trial and error. She, being an emotionally invested (though hardly passive) observer, goes down a darker, more harrowing path.

Some familiar stakes and tropes give shape to “Sleep”’s twisty plot: What’s to become of Hyun-su and Soo-jin’s baby, and what exactly does their nosy downstairs neighbor Min Jeong (Kim Gook Hee) know about what’s going on? There’s also some generic intrigue involving a shaman, Madame Haegoong (Kim Kum-soon), who comes recommended by Soo-jin’s anxiety-stoking mother (Lee Kyung-jin), and a medical doctor (Yoon Kyung-ho), who happily provides Soo-jin with placebo reassurances. 

To his credit, Yu also doesn’t shy away from the sort of generic encounters that you might expect given his focus on a somnambulist and his endangered child (Did you check the trash, dear?). But “Sleep” mostly concerns the subtle, episodic challenges that Soo-jin and Hyun-su face along the way. The trick to this type of movie is that you have to want to follow both protagonists as they realize that, despite their best efforts, they’re not exactly on the same trip. Yu succeeds by foregrounding and then consistently affirming Soo-jin and Hyun-su’s relationship even as they cycle through a horror story that puts them at odds. 

Better still, Yu never gets lazy in his portrayal of Soo-Jung, a co-lead who arguably has to not only be sensible despite her perpetually escalating paranoia but also scared in a way that makes her concerns seem like more than a collection of the usual horror movie pretexts. Jung’s good here, and so is her screen partner, but Soo-jung stands out in all the little ways that Yu emphasizes her motivating fears of losing her husband. It’s one thing to suggest that Soo-Jung wants to stick with Hyun-su no matter what. It’s another thing entirely to get a finely sketched but complete portrait of a stressed-out married woman through modestly scaled conversations with her mother, her partner, her neighbor, etc.

Lee’s fans will still likely see what they’re hoping for from “Sleep” despite the heavy expectations that come with his role, which happens to be one of his last. It’s not a very showy performance, but Lee’s still perfectly emblematic of what makes “Sleep” so special; he’s not only a commanding leading man but also a generous screen partner. He’s an integral part of Yu’s well-balanced big picture, just like the movie’s load-bearing scare scenes, which are never excessive or programmatic despite Miss Haegoong’s brief, overwhelming presence. Rather than end with a big supernatural showdown, “Sleep” climaxes with an emotional unburdening that, with a hard nudge in either direction, could have been laughably over-the-top or hilariously mean-spirited. It’s neither, because while Hyun-su inevitably airs her grievances, Soo-jung also (maybe) meets his wife at her level.

More than anything, “Sleep” stands out thanks to Yu’s delicate but surprisingly thoughtful consideration for both Soo-jin and Hyun-su, who complement each other even as they drift apart. “Sleep” also never overwhelms viewers with a tidy or heavy statement or prescription for what married life and new parenthood can or should be like. Rather, Yu stops exactly where he needs to to protect and maintain “Sleep”’s suggestive atmosphere and charming ambiguities. I can’t wait to see what Yu does next.

‘Deep’ Summary, Ending & Qratonin Experiment Explained

Thai film Deep builds its narrative around a neuroscience experiment that employs four medical science students. These aspiring doctors catch the adventurous but haunting ride of insomnia to earn some extra bucks. While the money looked green and glittery, they didn’t predict that sleep loss would result in terrifying visual hallucinations. Deep plunges into the world of Paranoia with divulging conclusions at the end.

Plot Summary

Professor Nichcha is a teaching faculty in a medical college. The film begins with her lecture on insomnia and its consequences. In the worst-case scenario, an insomniac can lose their ability to distinguish between imagination and reality. Hence, the dialogue subtly hints at the upcoming threat.

Jane is a bright medical student who looks after her young-blood sister, June, and her ailing grandmother Duangjai. Due to low aggregate income, Jane fails to repay the home loan and thus decides to quit her studies to exhaust herself in earning money. However, Professor Nichcha introduces her to a German pharmaceutical company for a part-time job that may solve her debt issues.

At Weimar pharmaceuticals, Jane learns about their ongoing sleep experiment, “ The Deep. ” The company implants a microchip on its subjects to extract Qratonin, which the human body creates to keep itself awake. Weimar wanted to use these substances to treat brain-dead patients through their experiment.

Director of Research facility at Weimar, Hans Miller, offers Jane 100,000 Baht for Deep Level 1 experiment. He plants the microchip on the occipital area from where it will extract Qratonin from the brain. The experiment will be deemed successful once Jane’s Qratonin level reaches 100 percent, monitored by a digital wristwatch. However, there is a twist to the all-sounding good plot. If Jane falls asleep for more than 60 seconds, the microchip may short-circuit and stop Jane’s heart. Thus, she can only sleep once the experiment is successfully completed and the chip is extracted.

Initially, Jane thinks that she is the sole adventurer on this suicide experiment but soon meets three colleagues on the ride. A party animal, Win, famous beauty blogger Cin, and the gaming nerd Peach, bring thrill and conflict to the fable.

Deep Level 3 Experiment

Money is numbers, and numbers never end. After successfully finishing Level 1, the four friends went for a Deep Level 2 experiment to earn more. But in the intermediate level, Cin faced a near-death experience that terrified the whole group. In school, Jane discovered a student who lost her life due to a “Deep Experiment.” Jane and her friends decided not to step in for Level 3, no matter what happens.

Jane’s grandmother suffered a stroke, and she didn’t have enough money for her treatment. At this tragic moment, she discovered that her younger sibling, June, had also taken part in the experiment. Jane tried to stop the young blood, but she was out of control. The money blinded June, and she went for Level 3.

Jane knew that her sister won’t survive it, and she argued with Hans Miller to remove the chip from June’s body, but he denied it. On the contrary, Hans extended an offer. In exchange for June, he wanted Jane and her friends to run for the experiment. Understanding Jane’s situation, her friends buckled up for the last ride.

Professor Nichcha personally supervised the four friends and gave them doses of Exerall every day to keep them alerted. But the visual hallucinations and Paranoia shook the hell out of them. At a crucial moment, Jane found that the whole experiment was a set-up by Nichcha. In the storeroom area, Jane found several surveillance monitors recording their activities and checking their vitals. Jane also found Hans Miller’s audition file that established that he was a mere actor and not a doctor. His real name was Jim. The mastermind behind Weimar was none other than her professor. But why?

Qratonin Experiment Explained

Win injected himself with CCL to cause temporary cardiac arrest. It compelled Professor Nichcha to unlock the door to the ward. She took Win’s body and extracted the microchip from his body, unaware that it was a trap.

At last, Nichcha spilled the beans and confessed her crimes. She enrolled the students into the experiment to extract Qratonin from their bodies to save her lover, Jed. 24 years ago, Jed jumped off the building in an attempt to kill himself (the opening shot of the film). He experimented on himself for research on sleep deprivation, but extended sleeplessness drove him into a fit of hallucination. Jed survived the jump but went into a coma. Nichcha found a practical way to extract Qratonin from the brains of sleep-deprived humans and inject it into brain-dead patients. Jed responded positively to the experiment, and Nichcha found a ray of hope for her lover.

However, Qratonin from a single person was not enough to awaken Jed from his coma. Thus, Nichcha created a network called Weimar to save him. She risked her student’s life for her own benefit. Due to her experiment, a girl lost her life, but regretfully, Nichcha felt no remorse. She was blinded by her own greed.

‘Deep’ Ending Explained

After her revealing confession, Nichcha tried to kill Jane and injected her with a sleeping injection. Win applied AED (Automated external defibrillator) and brought Jane to consciousness before her 60 seconds fled away. The friends reported Nichcha, and she was arrested.

Jane and her friends didn’t get paid for Level 3, but hopefully, their lives got saved, and the microchips were removed. They welcomed the peaceful sleep they had been yearning for. All of them found their respective closures. Win made peace with his father and accepted her mother’s suicide. Cin left medicine and joined a communication course, the journey where her heart belonged. Peach understood the importance of living with friends in the real world and started hanging out with his new gang. And Jane, well, she didn’t have much to do, but her sister concluded her late-night outings and started helping Jane with her canteen. Well, in the end, they all slept like a rock rather than sleep like the dead.

Deep is a 2021 Sci-Fi Drama Film directed by Sita Likitvanichkul , Jetarin Ratanaserikiat , Apirak Samudkidpisan , Thanabodee Uawithya and Adirek Wattaleela . It is in the Thai Language.

‘Sleep’ and Its Mysterious Ending Are Keeping Me Up Tonight

Sleep  (2023) by director Jason Yu is keeping me up tonight. I expected some random, unrelated spirit to be upset at the couple. But who would’ve thought that a stalker turned poltergeist would be so much worse?

What makes  Sleep unsettling is the movie’s way of morphing the truth. I’ve seen Soo-jin, the wife and mother, stay up late in fear of her husband, Hyun-soo. His sleepwalking had made their married life difficult, and it all reached the breaking point when Hyun-soo killed their pet Pomeranian one night while he was asleep.

But what if this isn’t just a case of sleepwalking? There are cases of sleepwalkers who commit crimes, but Hyun-soo has done other strange things during his sleep. Director Yu hasn’t given an explanation regarding the movie’s conclusion. You can use your imagination and interpret anything that’s transpired by the tail-end of the movie as you see fit.

If I’m the one putting on the thinking cap, I’d like to believe that Hyun-soo was suffering from a sleep disorder. Maybe there was a ghost who liked Soo-jin so much that he tormented her marriage with Hyun-soo. But there’s hardly any proof of that, other than a shaman saying that a ghost was inhabiting Hyun-soo’s body.

The sleepwalking theory is far more believable. Soo-jin’s experience with her sleepwalking husband was extreme because it’s rare for sleepwalkers to kill. These crimes happen, but as a former sleepwalker, I was far more concerned with snacking on a few biscuits. Additionally, Hyun-soo acts as if the ghost has taken possession of him and has promised to leave.

Some might think this was the real ghost, but Hyun-soo’s line of work in the movie was acting. He could have done this to appease his frantic wife, who was about to drill the head of their neighbor. Soo-jin lived in fear for her newborn daughter and her sleepwalking husband for months, so it’s likely that the stress had eaten away at her mental state.
