I work in a funeral home that's been around for over 100 years. I also work overnight. There's a lot of crazy things that happen. Mostly unexplained noises and shadows. The worst was when I was at my co-workers desk putting some paperwork away for her. Across the office was a door that leads to a hallway and up to the next floor. There was a shadow that looked like someone hesitating to walk in the room. The shadow would move into the doorway and then back away, then would appear on the other side of the doorway and back away again. I booked it. Freaks me out to even think about it (because I still have to go in there at night). There is no air vent over there or anything that could have been swinging around, wasn't the door either because it's heavy and couldn't be swingin' around on its own.
