Well, our hallway is lined with portaits and i swear i always see crap in the relfections, like whenever im walking down this one hallway, i can see the reflection of someone in all black sitting on the bed. happens alot.

Oh and when im home alone, i always here people walking up the stairs, cause it has a distinct sound. It scares the crap out of me. Cause like im usually in the computer room, and the entrance to the room is straight behind where i sit, and like then theres a hallway that intersects, i can hear people like walk by briskly, cause its like ten feet behind me.
