Yes, I vaguely remember that during college, one night I had a very vivid and elaborate dream in which I had flunked a test and was distraught wandering around school and various other things that I could not remember now, only that I was so distraught and depressed that after I woke up, it was several minutes before the realization came to me that it was only a dream and that I really did not need to be so depressed about that because that never really happened, it was only a dream.
