If the new trailer is any indication, the latest documentary from Rodney Ascher (last seen deconstructing The Shining with Room 237) is going to deliver what it promises: nightmares. The Nightmare takes on the peculiar phenomena of sleep paralysis and night terrors.

Here’s the synopsis; the doc will be out June 5:

The movie chronicles eight different people who suffer from night terrors and sleep paralysis, that finds them trapped in awakened states of semi-consciousness, where they witness truly horrific visions, but are unable to move.

Obviously the re-enactments depicted in the clip, which focus on the fact that the condition often means the sufferer sees a shadowy figure looming over his or her bed, are scary as hell. But despite their horror-movie (and video-game inspiring) qualities, night terrors are a very real medical condition. The Mayo Clinic describes them thusly:

Sleep terrors are episodes of screaming, intense fear and flailing while still asleep ... Sleep terrors differ from nightmares. The dreamer of a nightmare wakes up from the dream and may remember details, but a person who has a sleep terror episode remains asleep.

Sounds kinda Freddy Krueger, no? Pleasant dreams!
