Stress dreams

Everyone has stress dreams, right? Worrying about the first day of school or first day at a new job--maybe you dream you get there and realize you left your clothes at home. Maybe you have a presentation coming up that you're nervous about, and you dream you're totally unprepared. Or you're freaking out about meeting your significant other's family for the first time, and in your mind the family grows crocodile heads and try to eat you (no? Well that's good then). There are stressful times in everyone's life, and it makes sense that your subconscious would take whatever you're worrying about during the day and make it ten times worse at night.

So why am I having stress dreams about school?

Twice last weekend, I dreamed I was back in school (I graduated over a month ago). The first night, I dreamed I had to study for an all-important exam, but the power went out all over campus and I couldn't read my notes (also Chandler from Friends was terrified of the dark and wouldn't shut up about it, but that's not as important). The next night, I dreamed I was preparing for my Capstone presentation, but forgot about it. Then by the time I remembered and got to the presentation (which seemed to be happening in the hallway of my high school), there was no one there to watch my one-woman play (about pirates).

Stress dreams totally make sense when you're stressed about something. They're a way for your mind to cope with whatever's going on to stress you out. But I'm not stressed out. Yeah, Dave didn't get the job he wanted, but that's really not going to affect our day-to-day life. It's not really even affecting the wedding that much, since at this point we don't have a wedding--just some half-formed ideas. I have very little responsibility at work, so it's not like I have anything there to be worried about. And I've been out of school long enough that I shouldn't have any stress left over. I didn't even have school-related stress dreams when I was a student--so why do I now?

Do school stress dreams last your whole life? Or, even worse, do they get replaced with other stress dreams? Are there crocodile heads in my future?
