I do something like this occasionally. I don't yell or anything like that. It usually happens as i'm going off to sleep. I awake scared shitless and just about every muscle in my body is tensed up. Feels like i'm falling. It takes a few seconds to realize where i'm at. :happysad: Doc said it's called a "hypnic jerk". Nothing you can really do about it.

I've even pulled it off in class a few times in HS :chuckles: <---- Gee, that really sounds bad if it's the only thing of my post that you read.
