I don't know the name of this phobia and I can't seem to find it, but lately I've been thinking a lot about it. For example, every time I go into the bathroom and the shower curtains are closed I just have to open them because not seeing a part of a room makes me uncomfortable. Another thing, when I was on vacation once there was these curtains covering the side of the bed so you could close them off entirely, however that makes me uncomfortable as well, so I simply slept with them open. I think it's because there is a potential "possibility" of somebody jumping you from behind the place you can't see, even though you KNOW there is nobody there.
Anyone have the same phobia? Know anyone who does? Is it common?
