in my old house if you left the door open it would slam shut. This may sound like just the wind but than we started putting bricks in front of the door so it wouldn’t close. But than when we would leave the door alone it would still slam shut and the brick would be moved. We didn’t understand at first. And now this may sound like bullshit but im telling the truth… When we got home one day i was sitting on my bed. Next minute i feel someone sit next to me but when i look over there is no one there. (I had a double bed and i was on the very right.) and there was a dint in the bed as if someone was sitting there. Trust Me i was never so happy about moving houses.
