Sleep paralysis and night terrors are shockingly common. Stuck in states between waking and slumber, brains create demons. Great idea for a movie!

Sleep paralysis, closely related to "night terrors," is a scary and surprisingly common condition. People who suffer from these conditions find themselves in a state somewhere between sleep and waking life. As a result, their brain works, but their body refuses to move.

To make matters worse, most sufferers of sleep paralysis report sensing a threatening presence in the room. In some cases, they may even see a dark figure or feel someone crawling on top of them. The inability to move only lasts for a few minutes, but it is nonetheless terrifying.

Needless to say, this condition makes for great horror movie material. In fact, dozens of horror movies and TV shows use characters suffering from sleep paralysis, and most of them will make you want to sleep with the lights on. So, let's take a look at the 10 best sleep paralysis movies (according to IMDB).
