Baldwin-Wallace, the school I went to for a year, is a VERY haunted campus. The primary place is Kohler Hall, which I was going to live in for my sophomore year until I decided for sure a few weeks before going that I hated my major and wanted to take a break and withdraw. Kohler is in the top 10 most haunted places in Ohio.
It was originally a civil war hospital, then a part of the Underground Railroad, a psych institution, an orphanage, and a morgue. Right across the street from it is a sanctuary, and there's an underground "road" connecting Kohler to the church. The tunnel was used to take the dead to the sanctuary to be buried during the war. It has since been closed off due to student complaints, but it's said that you can still see a faint blue mist surrounding it (the basement, which was the morgue during the war, is still open).
There was a girl several years ago who, against regulation, had her boyfriend spend the night. She sat up screaming, had bloody, violent scratches ALL over her arms (she had not been scratching herself), trashing, ended up getting out of bed and running up and down the halls screaming, and then went back to bed like none of it had ever happened. They took pictures of it, and I don't remember if she said it, but it's said that she was attacked by a ghost in her sleep (she resided in one of the haunted rooms).
There's another room where there was a little girl who lived when it was a psych ward. She ended up dying because her parents couldn't afford the treatment. Her parents donated a hefty sum to the hospital, and they put a plaque on the door of where she lived. To this day, they've repainted, replaced, sanded, everything, and the plaque still stays there, and it's said that you can hear the little girl in the room, opening drawers, whispering, etc. She's apparently a friendly ghost.
There are a few other very violent ghost stories, but I don't remember what they are.
The astronomy tower is very haunted, I don't remember what the story is. I just remember it was a VERY violent story, and it's dangerous to go in there after hours.
There were a ton of other buildings that are haunted, but I don't remember them all. During orientation they held a haunted campus tour and told us all of the stories of all of the haunted places. It lasted a few hours, hah.
