It must be a week for this kind of stuff. I had another friend last night tell me about experiences where he has been pinned to his bed (quite scary apprently) twice by some force. He's not sure if he's awake or asleep, but he does wake up when he can move. The interesting thing is that it's also happened to his sister and her boyfriend in the same house.
I'm sure by the end of the week, someone else will share something like this with me
