Had a dream I had to retake a math course my senior year, yet all of the seniors were in it, and I had missed several days, so I didn't understand what was going on. Took a 60 second test (which seemed to last for an hour), couldn't get one answer because I didn't understand anything that was going on, so I was trying my best to try and figure out the problem through common sense, even though the question (can't remember it) made no sense what so ever.
Dream ended, it was short and pathetic. Whenever I have a dream relating to a course/class, the room is always dimly lit, and I really don't know why. I always wake up nervous, though.
