The haint thread got me thinking. I did it once. HS. I was a jr.. On an exchange no less.. Apparently I got into the kids parents room I was staying with and was rambling something incoherent, then just left and went back to bed. Very vaguely remember it happening. I know little kids do it. A friend walked off his loft in his sleep and fractured his skull and was never the same after. Fell 10 feet to a concrete floor.
