And it turns out to be my daughter! Last night I was sitting at the computer late at night, and I hear a knock at the computer room door. It's my daughter, looking like she's half awake. She starts to have a nonsensical conversation with me- something about asking me not to leave my mouth open when eating lunch at her school! I simply told her OK, and that she could go back to bed now. She smiled and said OK, walked back to her room and went to sleep. Didn't remember a single thing in the morning! It was amusing as hell, and also weird as all get out! Anyone else deal with a sleepwalker in their life?
