Just read through this whole thread (it's awesome!) and thought I would contribute.

While exploring friley with a friend, we came across the 'haunted dorms' in the basement near Dodd's. We turned on the lights (cuz they were off in that part of the hall) and walked down to the dorms. The temp rose and we actually started sweating, then noticed on one of the doors is written 'satan's legion' among other things, we got freaked and ran like hell. Then about a week later I was showing another friend the dorms and we were stopped by some guys that live in Dodds, they told us that they weren't really haunted, just that the rooms were closed because the windows are too small, and considered a fire hazard if some one needed to escape. I don't know if this was just to make us feel better, but I definitely got the creeps while being down there.
And I've heard stories that the only room where a student hung himself was on 5th floor.
But on to a more exploring aspect, I've heard that there is a way to get to the attic of Friley through a room on the 5th floor. There's not much up there, but still sounds cool.
