I sometimes have a dream that I've gone through several months of high school without realizing that there was a class I signed up for but never went to. After finding out the horrible mistake, I'm guaranteed I won't be able to catch up, and my school career is over. Seems like an extremely unlikely scenario in real life, but I've had the dream more than once.
