Supposedly, we all dream every night, though we may not remember it. Dreams last only a few moment of intense REM sleep, though they may feel as though they have gone on for hours.
I had one of those dreams last night, in which I was visiting a campus in some other state, something like a cross between Florida and Indiana... bizarre hybrid! I had with me my son, who was about 11 or 12 and my mother, who did not have dementia in the dream though she did in real life, but had a broken hip and difficulty walking (she never had a broken hip though, that I recall, in real life).
I was in the bookstore buying something, and the cashier told me to take care of my son. I looked around, and he was gone. I didn't seem too worried about it though.
I ran into my mother, having a snack at the cafeteria outside, and I just left her there, went out and got on a bus, though my car was parked somewhere. A block later I realized I had left my son and mother behind, and jumped off the bus, but found I was in a completely unfamiliar part of the campus. I started going into all the buildings, but never found the ones I had been in before, where my son and mother might be. One building was the gym. It was particularly strange. To get into it, one had to climb a wooden staircase that moved and swung loose in the air as one climbed. It was frightening, and I didn't make it more than two steps before I jumped off. I knew that wasn't the right building anyway.
One place that looked like an underground garage was actually a florist's shop, where, in the half-darkness, thousands of flowers glowed. I never did find either my mother or my son.
