I had a dream last night about having an appointment to some kind of unpleasant dental procedure, and I simply didn't show up, and I began to worry they would bill me for the time the doctor was waiting there for me, so I snuck in the next morning to the dental office. One of the assistants was there setting up, and although I walked up to her, not quietly, she didn't hear me.. I wondered if she was deaf. So I walked to the chair the procedure was in, sat down, and was going to wait until they came in, somehow thinking that would make it alright.

I think it was a combination of dream logic, and that old perverse sneaky guilt logic that we all had as kids and (hopefully) have learned to supress. I wish I remembered it well enough to dissect it -- it's fascinating stuff.
