A few years ago i lived in a house that was clearly haunted. One night i woke up for no apparent reason and became aware of a strange atmosphere in the room, my eyes were drawn to the door for some reason, the door was opening slightly and a clear cylinder 3d sort of shape (about the size of a shoebox) hovered around the door, this stayed hovering for i would say 20 seconds or so and then it went out of the room. The whole time I was completely frozen with fear and could not move even for a good while afterwRds. I wasnt drunk wasnt dreaming and wasnt on drugs. This actually really happened to me and a similar thing happened again in the middle of the day and my dog also saw it. Needless to say i was happy to move house not long after.
