I have the "naked/in underwear/wearing pajamas at school" dreams pretty often. But the craziest school dream I had was where to graduate you needed to traverse with a partner through an abandoned mall type area called the "dreamlands", which was an accepted part of how schooling worked, within the logic of the dream. I managed to get through and when I was on the bus home (totally alone, I guess I was the only one who survived?) there was a hurricane going on (it was going on during the test too) so I just rode home in silence in the middle of crazy wind and rain... Every other student died I think
