I lived in a house that was rumored to be haunted by its previous owner. Built in the 1930s, it had some nice historic features like a kitchen door that swung both ways connecting the kitchen to the living room. Beside this door in the living room was a heavy vintage-style bar/liquor cabinet. One night when I was alone in the house, I went into the kitchen to get some wine, pulling the swinging door closed behind me. When I went to push it open again, the bar had silently shifted about three or four inches over, blocking the door. If the bar had been in that position when I entered the kitchen, the door wouldn’t have closed. I was eventually able to push my way out, but made a point to never close the swinging door again.
