Yes I get that feeling too! I HATE going in to our basement, it's not finished so it's all scary concrete rooms and stuff and then there is this "secret" room that the Lambda Chi's made when they lived there and there's no windows or anything in it and the floor drops like two feet and it just looks like a big dark hole.
Also I hate going up to room 301 in our house b/c apparently a girl died in there, I don't know how true that is, but still I think that area of our house is haunted so I avoid it as much as possible.
There is also this spot on campus by the hospital right before greek town and there are NO LIGHTS in the stupid parking lot and I used to always have to walk through there to get home. I hated it and I never go by there anymore, but seriously it looks like the perfect place to get attacked. Yikes!
