I have some strange experiences myself.
First time I was sleep walking into bathroom and on the way back I wake up my mother to ask her where is my sister, but I don't have a sister.

Second time I was sleep walking around the house searching for something, but the entire time I was seeing everything without able to control my body, it's like I have been possesed by a spirit. I even heard some weird thoughts in my head, "that is not my house; is this a dream, will I be able to fly out of the window;"(thank god he didn't jump out of the window). After a while suddenly, I was able to control my body again.
