Can't do anything correctly?

I've had three or four dreams like this over the past few weeks- I dream that I'm doing something simple (Taking a picture, buying a movie ticket, others I can't recall but know I've had) but cannot seem to get it done. I either can't decide what to do, or something is malfunctioning. I always wake up before being able to do what I'm trying to do. I'm always in a situation where I 'm embarrassed for what I can't do. I dreamed I was trying to take a picture with a celebrity but my camera kept messing up, and a girl at the movies was staring at me rudely for not being able to decide what movie to see.

I'm fifteen and I used to have pretty severe anxiety disorder, and lately I've felt like it could be returning. This scares me a lot. Do you think my dreams (which are so recurrent it's beginning to take a toll on my nerves) are just a way of me expressing my fear of becoming anxious and scared of the public again? Or have you had/heard of dreams like this and have a different explanation?

Thanks :)
