I have been paralyzed before laying in bed with my eyes open and have seen dark shadow figures, like a shape of a human, darker than the night sky, darker than the darkest darkness you could ever imagine, the ones i have seen, make awful noises and another time they were swearing at me too, another time it felt like they were lifting me up off my bed and going through my body, scientists, doctors know this as sleep paralysis, but i'm pretty sure they were demons, it's the devil's way to steal people's sleep. Call out the name of Jesus if this ever happens to you, and it will leave.
