I don't have any advice but something similar happened to me and my wife many years ago. She had a bad dream and was actually hitting and pinching me in her sleep. The next morning after we woke up I asked her about what she was dreaming because she was hitting me. She told me that I was being mean to her in her dream. I didnt think much about it because it was just a dream. She stayed mad at me for a week because of what I did in her dream.
Holy Crap ! Same here... . More than a couple of times.
I can Laugh about it now... . But back then... .Imagine being forced to apologize for something I did... .in HER DREAM... . Talk about a mind screw.
