While I was in college, I lived in a college apartment for one year. I don't think it was a very old apartment building, and if anyone had ever died there, I was certainly unaware. I had three roommates - two of whom had lived there the previous year. The girl in the bedroom right next to mine moved in at the same time I did.
Once we moved in, some strange things started happening (the other two roommates had said that nothing like this had ever happened before). It started with the TV in the living room. The four of us were sitting on the couch, watching TV. The remote was sitting under the table that the TV was on, upside down. The back was off of the remote, so we could see that there were no batteries in it. The volume on the TV was a little too low, and I commented on it, asking anyone to turn it up. Of course, we were all too lazy to do it, so we just sat there. However, the volume bar on the TV started to go up, and remarkably stopped at a comfortable volume. We were all pretty spooked, but it didn't scare us too much. After some discussion, we had decided that if our apartment *was* haunted, it was probably haunted by either a kind spirit, or one with a sense of humor.
After that, I started hearing strange noises at night. Not like noises you would expect to hear in a college apartment complex, but very mechanical "ticking" noises. The part that really got me, though, only happened one night in my bedroom. I was in bed, in the dark, trying to get to sleep, when I heard a loud, "THUD," on the wall behind my head. Immediately after that, the following things happened in a perfect clockwise circular pattern around my room:
The mirrored door on my closet shook. Right after it shook, my bedroom doorknob (just to the right of it) began turning rapidly. That stopped, and my bathroom doorknob (just to the right of my room door) turned rapidly. After that, my VCR, which was to the right of my bathroom, turned on and then off by itself. The window to the right of the VCR then began to shake. Then the thud behind me again.
This circle went around three times, and then stopped.
I had no idea what was going on, and I had absolutely no explanation as to what was making the noises. Nobody else had any experiences in their bedrooms, and I didn't have any more after that, but the TV in the living room was still affected.
I've long moved out since then, but I still think it was an interesting story. Also, I was interested in theories on what, or who, was in our apartment.
