I was living in a house in New Albany, Indiana. I had rented a room in the basement, and my room only had one light source. Despite the fact that I had only one light source, and could clearly see if there was anything in front of it, I would frequently see unexplained shadows moving across the walls. I always felt kind of creeped out at that place.
Eventually, a man who had been a healer in the Creek tribe came to live in the house. One day he approached me and said "hey, man, we need to talk."
"Talk about what?" I asked.
"About the things flying through the air."
Right about then, the shadows began moving on the wall. "You mean those?" I asked.
On another occasion, I was in the bathroom shaving, using an adjustable mirror, when I saw a girl, probably a teenager, leaning against the doorway to the bathroom. I tried talking to her, and she just vanished.
Eventually I asked the other people in the house about these happenings, and they all had stories. One person regularly saw people who appeared and vanished. One woman would leave the house having turned her computer off, only to return and find the computer turned on, and weird, cryptic messages typed on the screen.
Commentary: In many ways, this is a typical haunted house story - the house is host to many different repetitive events, none of which appear to be connected to each other, but all of which are found in the same location. Unlike many other haunted house stories, the events appear to have happened to each person uniquely - nobody experiencing anyone else's weirdness - although there was the shared experience of the shadows on the walls.
Regardless, the odd personal stories instead of a single communal story or single theme for the stories is interesting. What it means, if anything, is unclear.
