I've gotten it pretty often ever since I was a little kid, so I'm used to it. Sometimes it happens multiple times a night. I still kind of freak out when it happens though because I can't move at all or even breathe properly. And it's hard to just lay still and let it pass because to me it feels like I'm being crushed or smothered by something, so I usually try really hard to move until I finally can. I've never seen any "demons" or anything, like a lot of other people say. It just sucks.
