In one dream, I was trying to find my way out of a huge shopping mall. I was remembering little aphorisms, one of which was all about the importance of the fourth floor. The exit, including a Metro exit (must've been Montréal), was in fact on the fourth floor. I guess my inner Discordian was asleep at the switch in picking the floor.
In another, I was talking to a doctor who told me that my heart was not working right and that I would not live past 60. That's some pretty slow heart disease, I guess, but I felt really crushed in the dream knowing that my life was half over.
In a third, the recurring test/course/whatever that graduated students all dream about missing, remembering and realizing that their graduation was null and void, all for the want of a French credit, had the academic thing replaced by a vet appointment.
