What position do you sleep in? Since I was born, I've slept the same way-on my stomach with my head facing the wall. My friend says I'm lucky to sleep that way because it helps prevent sleep paralysis and nightmares. He sleeps on his back and gets sleep paralysis constantly as well as nightmares almost every night. He says he can't help it because if he sleeps on his stomach he can feel his heartbeat and it creeps him out.
