Devil in the Room is a terrifyingly illustrated documentary about sleep paralysis. The phenomenon, in which awareness and nightmares collide, may explain legends of demons and visits from extraterrestrials. “It doesn’t matter if it’s real …because it feels real.” And because of the paralysis, you can’t do anything about the situation, which adds another layer of terror.
