my ex used to do this but while fully asleep, she would actually have conversations with me while dreaming, as if I was in the dream I suppose, properly weird, used to confuse the **** out of her when I didn't know what she was talking about. She is a full blown mental though.My missus can have conversations with me whilst she is half asleep and then usually doesn't remember them. I find that this is the best time to see if she minds me spending lots of money on computer parts.
