I usually have nightmares, sometimes scream in my sleep, and people tell me in the morning, but that's probably drug enduced.
But apparently when I was young, about 8, my mum said I she heard something in the livingroom at night, and she went in and put the light on and I was rocking on the rocking chair saying "Where's the house?", wee bit creepy, I don't sleepwalk anymore, not that I know of anyway.
