I used to get the horrible fear that someone was waiting for me to fall asleep in my room when I came home and kill me. I knew it was irrational, I knew it was stupid, and I knew that the possibility of that happening was slim to none. But that never stopped me from checking the closet before I went to bed, and putting a chair on it so I would wake up if someone tried to come out.

Wow...that's the first time I've told anyone that. That sounds paranoid as hell.

Anyway, I don't do it anymore (when I'm sleeping in a room with someone else I don't have this fear whatsoever), but the thing is that sometimes the fear would become so great I wouldn't move. I'd just lay there in my bed, too afraid to do anything. I'd definitely attribute this to anxiety.

So in short, to answer your question: Yup. Seems anxiety related to me. Maybe some GAD in there? Worried about all the 'what ifs' and stuff? I have no idea really, I'm GAD so I thought maybe that would be it, but either way you should get this checked out.
