Sleep paralysis is the terrifying feeling of being held down after just waking up or going to sleep. You can't move or scream, and sometimes this paralysis is accompanied with the certainty that someone --or something -- is in the room.
I've had it happen twice and it felt like i was going to die . I could literally see a demon holding me down . My sis just happen to walk in and jump on me and saved me . That shit is scary as'f i swear .
