Shelly...I did the same thing. I punched my x-fiance in the back while we were sleeping. I was dreaming that I was fighting one of the girls that he had been secretly talking to while I had been working and going to school full time. Not long after...I completely kicked him out of bed.
An awful way to be woke up I guess....but I didn't feel too bad because I was supporting us both and he had starting getting physically violent with me while withdrawing from pot because he starting drinking instead. I guess I couldn't bring myself to fight back while awake so....my unconscience did the butt kicking for me. lol
(It may sound like it, but I'm really not a mean person...he just REALLY deserved it!)
