dude, i know how you feel, the same thing would happen to me, exept it wasn't a face in the window, it was a figure, like a soldier outside of my room. I would get so scared, start to get up, then just stop and fall in my bed. I was so scared, then my cat came over (RIP Whiskers). It was wierd and i know how you felt. I think that the other guys might have hit the nail on the head about this though.
