I have always had vivid, complex dreams, and I can normally pinpoint what is contributing to them. For instance, before my dermatologist appointment, I had the tentacle-mole dream; before my GYN appointment, I dreamed I picked at a pimple-like bump on my breast and a big hole opened up and the contents of my breast fell out and turned to yellow dust. When I have a little guilt over being such a bad correspondent with my friends back home, they show up in my dreams. Thanks for the reminders, Subconscious!
But there's one frequent dream-and-variation that has left me scratching my head. Try to imagine, if you will, the dirtiest, nastiest, most disgusting public toilet you have ever encountered. Now multiply that by 30 stalls, none with doors, paper, or seats, and most containing floaters. Now find one toilet you could talk yourself into hovering over, but then notice it has no or low walls and is in the middle of a busy public thoroughfare or a men's locker room, after you've pulled your pants down. I have this dream all the time. This morning, I finally realized what it is: the don't-piss-the-bed dream. Despite peeing every night immediately before bed and being a light sleeper--light enough that needing to pee would definitely wake me up--my Barbie teacup-sized bladder has joined up with my subconscious, and they have decided not to take any chances on an adult bed-wetting episode, hence the yuck-tastic dreams.
I'm going to the dentist next week. I'm sure I will have a nightmare involving giant tooth-zombies.
