I have this recurring dream (seriously, I've had at least one every couple of months) that involves me being enrolled in a class I'd forgotten about... or were aware of, but never went at all for some reason, that's also required for me to graduate. In all of these dreams, I'm already accepted and ready to go to some program after graduation... and it's one stupid unrelated class that's going to keep me from going.
I had one about missing a whole semester of PE classes and being about to flunk out of high school just a few months ago.
Last night, I had a dream that I was enrolled in an English class and I'd missed the first 1/3 of the course. I was about to leave for school, and I came to the realization that I hadn't been going to class. I was almost late for class, but I realized that I hadn't read the book that I was supposed to... and it was a major exam that day! So naturally, I decide it'd be better for me not to go... all the while, anxiety was building and shooting out the roof.
I graduated college 2 years ago, and I still get these nightmares... and EVERY TIME, I wake up breaking a cold sweat.
Sorry, quite off topic, but I definitely have my freak out moments for very random things!
