A newlywed couple, Hyeon-soo and Soo-jin, are as happy as they can be together with their adorable little fluffy dog. That is, until one night Hyeon-soo starts sleepwalking, and acts in ways that are totally unlike him. It all keeps escalating, to the point where Soo-jin fears that he will harm either himself or her. Soon, they also have a baby on the way…how can they make sure that his sleepwalking stops being a threat? And is it all really just a simple case of sleepwalking?
Sleep is a South Korean horror thriller from 2023, written by Jason Yu in his feature debut and stars Jung Yu-Mi and Lee Sun-kyun. This is one of the final films that Lee Sun-kyun starred in, as he died the same year after an incident of drug use allegations, charged on suspicion of using cannabis and psychoactive drugs. He tested negative, which probably should have been the end of that if it wasn’t for South Korea’s high moral expectations of public figures, and a very strong social disapproval of drug use. On December 27th, 2023, he was found dead inside his car with a charcoal briquette in the passenger seat, which is commonly used in suicide via carbon monoxide poisoning in South Korea. So this gives the movie an even darker sentiment than from the subject matter alone…
Now, Sleep has a premise that may sound a bit simple, but the film manages to deliver an overall suspenseful story. You keep wondering if the husband’s sleep disorder harbors something darker and more dangerous, and as the movie progresses you’re not really sure what to expect. There are some incidents which proves that Hyeon-soo’s sleepwalking incidents are far more than a mere nuisance, where no one is safe. The husband is a loving and good-hearted person while awake, but once he sleeps, there’s no way to predict what he can do. At first, the couple tries everything…making him go to bed in a sleeping bag in the hopes of him not being able to get up and start his sleepwalking shenanigans, an attempt that proves to be completely futile. Soo-jin is at her wit’s end, and place a bell at the bedroom door so she will wake up when he leaves the room. And soon, the sleepwalking becomes a danger to everyone. In some ways, I think Hyeon-soo’s sleepwalking and the fears and danger Soo-jin is placed in because of it, can be a bit of an allegory to living with someone who’s a substance abuser or someone having a mental illness that changes their personality and behaviour drastically. Soo-jin never knows how dangerous things might become when her husband falls asleep, and lives in constant fear of what could happen. Her own sleep is totally disrupted since she can never relax, being watchful every night of what her husband might be able to do once he’s in the sleepwalking state. The tension is very palpable due to the strong performances, and you feel sorry for them both.
Sleepwalking is not a theme that’s got a lot of horror movies dedicated to it, so far we’ve only seen the Swedish 2000 thriller movie Sleepwalker which deals with the same subject matter. Thus, Sleep is another entry into this genre, a suspenseful thriller powered by strong performances, where a man’s sleepwalking habits turns him into a danger to his own family.
