When I came to orientation, our group leader told us that the AI building was haunted. He said that late one night, a janitor was cleaning up and tripped over some equipment on the floor. In doing this, he fell into some of the machinery they used to kill the animals and got hacked up pretty bad. He made his way to the elevator to try and go get help, but died inside before he got to the first floor.
Personally, I always kinda try and walk a little faster if I have to pass by the really old buildings at night. I had a classroom in the basement of the old civil engineering building my freshman year, and it always totally freaked me out. Are there any stories about the chemistry building? That place is bound to have some tales.
My grandpa had told me some stories that people would hear and see strange things in the old hospital building, but now it's gone.
