We've all had version of the dream.

For me, it's one of two versions: I'm back in school and woefully ill-prepared for a test, or it's now and I have a job but for some reason need to attend classes for another term, and I have no idea how I'm going to work that in to my travel schedule or family life.

But why? What's it mean?

Psychologists think it's our subconscious memory dragging up old stresses, possibly in search of a coping clue for how to deal with a current anxiety. This particular dream - and why it's so common - has a lot to do with a fear of measuring up.

Therapists say we should identify what's going that provokes the anxiety and in my case, it's not hard: new job, new organization.

So now I know.

Thanks Bill Zucker for this.
