SLEEP follows newlyweds Hyun-su (Lee Sun-kyun, PARASITE) and Soo-jin (Jung Yu-mi), whose domestic bliss is disrupted when Hyun-su begins speaking in his sleep, ominously stating, "Someone's inside." From that night on, whenever he falls asleep, Hyun-su transforms into someone else, with no recollection of what happened the night before. Overwhelmed with anxiety that he may hurt himself or their young family, Soo-jin can barely sleep because of this irrational fear. Despite treatment, Hyun-su's sleepwalking only intensifies, and Soo-jin begins to feel that her unborn child may be in danger.

Combining drollness and dread, writer-director Jason Yu offers a subtly unnerving exploration of marriage in Sleep.

This is a really fun, tight little thriller that accomplishes a great deal in a limited space.

Sleep is a wild ride, but it refuses to lose sight of the emotional state of the people it puts onscreen, even as they fall apart.

4/5

Though its commentary on the ills of modern society can often feel a little redundant, the stellar performances and a suitably twisty narrative carries Sleep into its head-scratching, bonkers final act.

3/5

With tight camera shots and a setting primarily within the couple’s small apartment, the film draws viewers into the intimate confines of their relationship, where trust, fear, and paranoia become inseparable.

3.5/5

Sleep is a great reminder that across cultures, we still like to be in control of our lives and that a loss of that control can feel frightening. And that at the end of the day, all any of us want is a good night’s sleep.

You’ll get answers which is rare with slow burning horrors. Most of the story is shot in one place and it works wonderfully. The film gets extra credit for this. The only drawback is the frustration I felt towards the main characters actions.

Again, if a horror film is told with a good story, and each character is played well by the right actors, it will be a good film! A simple film about fear that leads to madness, SLEEP is proof that you don't need jump scare to making terror! 🔥🔥🔥🔥

It could have been just silly but it manages to go really crazy. It makes you doubt if it it's a ghost or madness story in the end and the sleepwalking episodes were really creepy. And the third arch scenario was absolutely amazing

Sleep went way beyond what I had anticipated and told a story of a struggling young couple. Don't eat the dog.

Presented in Korean with English subtitles, SLEEP is a tautly structured ghost story that melds the uncanny with the ordinary.
