Do you have a scary room in your house?

[Ming-Yan]

The Attic [my room]. My door opens and closes by itself. When it closes, it slams and the trees outside make weird shadows because the ceiling has slanted ends on both sides. (like a trapezoid)

There is also no air conditioning in that room, sometimes in the middle of the night the light outside the room turns on and no one is there, but after a while they go back off. I think it's probably just someone but who goes to the attic 2 in the morning?
