When I was a freshman at point park university, there was a well-known ghost in the dorms, which was an old hotel. The ghost was called "the shuffler," and it sounded as if someone was shuffling across the carpet. We would hear it in multiple peoples' rooms. The weirdest part was that you could follow the sound around the room. It always sounded like it came from the doorway, moved around the room, then back to the hallway. The creepiest time I heard it, I was in my room with my roommate. We were both on our beds, on our laptops, when we heard it come in from the doorway and walk to the window. Out of nowhere, the window blind shook. Not like a little bit, like someone grabbed a hold of it and shook it. It was pretty weird.
