Thread: Waking up and talking out loud

Not sure if this is the place to put it as it is a recurring thing, but over the past few months I've had the experience of waking up with the feeling that I have to say something out loud... and I mean HAVE to say it.

I don't know why, because I gain consciousness and can't remember what or why when I try to think about it, but I have to actually fight to stop myself talking gibberish out loud, and I always feel really tense and nervy afterwards...

Anyone else do anything similar? Any ideas what it might be? My only theory at the moment is some kind of hypnogogia akin to sleep paralysis - any thoughts?
