Sleepwalker/random whatever here as well.
Andrew will say to me, "you really freaked me out when I came in the room last night." I'll ask why, and he'll say, you were sitting upright on the bed and gave me this evil look. I asked, what? and you just tracked me with your eyes until I walked out of the room. This is after I've been sleeping.
I still wake up at night sometimes thinking I see someone standing in the room (usually a dark human-form shadow) or think I see something moving. When I lived with my parents down in South Georgia, I had the same shadow-form in my room about two feet from the foot of the bed on the side I slept that would just be there (so I thought.) When I moved north for college, I never saw it again. Who knows?
I particularly remember a sleepwalking episode in which a friend of mine was spending the night with me. I woke up...walked to the light by the door...turned it on, and when she woke up and asked, "what's wrong?" I said, "Shhhhh - everything's going to be allllll right," and then I turned the light back off and went back to sleep. The next morning she looked awful. I asked if she slept okay, and she said, "no, you freaked me out!"
Sometimes when I wake up, I remember doing things...other times not so much.
I think my mind gets in overdrive
