I've had a few nuclear war dreams. Strife all around me, but I'm always just fine, not even ruffled feathers, albeit sometimes requiring relocation and/or a slight inconvenience.
Last night I was alone in the lab where I last taught, cleaning up by putting away glassware and temporarily removing a piece of equipment from the hood and replacing it there. On the way out I met Dr. Love (department head) and, realizing I should not have been there, explained that I must've sleepwalked there after stopping at the previous place I'd taught. But before he could respond, I was saying, "But you don't remember that, because I just dreamed it, didn't I?" And the room changed a bit as I "woke up" and saw Dr. Love again -- this time talking to another faculty member in the hallway -- and started to explain again that I'd been dreaming, before realizing I was still dreaming, because how could I have walked so far? Well, that's OK, I've walked here before...no, wait, I only dreamed that I'd done that before. I realized the geography of the two schools (plus my being back at my previous home) and even the weather were screwed up, and I "woke up" again. I lost count of how many times I did this, dreams nested inside similar dreams. Then I realized I needed to use the bathroom...or was I just dreaming such a need? I decided that because of the possible consequences that I had nothing to lose and could only gain by waking up, so I did, this time for real...and immediately had to go to the bathroom.
