In the middle of the night I heard a banging from inside a closed guest room at the end of the hall. The hall light was burned out, of course, and no windows. Something was banging on that door like in a horror movie. The banging stopped just as I reached the door. My heart was pounding but I HAD to open the door, in the dark. It was the damn cat trapped in the room. Scariest thing ever. Reminded me of the movie "The Woman in Black."
