Sleep Paralysis
This only happens at my dad's house though.
Oh stuff son, you got a gherst on your hands.
But otherwise. If it is Sleep Paralysis. I hear some good ways to prevent Sleep Paralysis
1) Sleep on your Stomach. So if you get Sleep Paralysis at least you won't know the forget is there. And it sometimes prevents the entire thing from happening!
2) Have someone be with you in the room while you sleep. So if you get Sleep Paralysis then they can come over and snap you out of it.
3) I forgot this one. I don't think there is a third way.
