Me and boats have been in and out of there a rather large number of times. I was a childs hospital and an elderly persons home and I think also war veterans in its early days, with only a small amouont of rooms set aside for patients needing 'extra' care. I used to work with a woman who worked there, its not been closed that long. No ghosts, no ghouls, no nasty stories of experimentation or torture.
You're just a big girl.
Also, did you find the enterance to the basement? If you wanna spook yourself thats where you wanna be going.
