A few years ago I lived in an old apartment above a restaurant One night, I had a friend over and we were up late talking about ghost stories. She told me about some creepy experiences she had ghost-hunting. She left around 3am and I tried really hard to go to sleep. I was still a little spooked and laid awake focusing hard on the ceiling lamp when suddenly I saw the light turned itself on. I have never been so scared of a light turning itself on. That doesn't just happen right?! I called my friend instantly and we talked on the phone for a bit but I was too freaked out to turn the light off or try to sleep. Eventually as it started to get light out, the ceiling lamp clicked back off. Nothing like this ever happened before or after this. The building was old and there were a lot of weird noises there but this was an isolated incident. Eventually I moved due to a rat infestation that didn't effect any of the other units and apparently disappeared as soon as I moved out.
