Hey, cool username man. I was researcher phobias recently, particularly when I realized I kind of had one, which I later identified as Claustrophobia. It's actually kind of odd how similar that is to Agoraphobia, as they both deal with spaces you can't (or that you perceive you can't) escape from, just one deals primarily in closed-in spaces, and the other in open spaces.
... Yeah, random. I just find your username fascinating. :xd:
