Not sure if stuck/paralyzed is the proper term for this post. But at times while I've been asleep. I suddenly wake up but can't move, talk, scream, or breath. It's as if I'm glued to my bed. It's happen several times to me already. The weird thing is that it only happens when I fall asleep downstairs on the sofa. It's never happen on my bed. Last night I fell asleep on the sofa again. My wife woke me up and asked if I was staying downstairs. I told I'd be up there shortly. After a while I dozed on and off as I was watching tv. Then all of a sudden it felt as if someone sat next to me on the sofa. I turned and looked but know was there. I quickly got up and figured I'd better go up stairs. Can anyone explain what is happening?
