I had that dream again last night, the one where I'm out in public doing something completely normal, like getting coffee with a coworker, and I am completely naked. Sometimes there is a reason for it in the dream, like it is too hot outside, but other times I am just naked for no apparent reason and belatedly realize that I have no clothes on and this is not a good thing. The ending is always the same - I just act like nothing is out of the ordinary and hope that people don't notice, and then I wake up.
Another recurring dream is the college math class dream. This is the one where I have signed up for some advanced math class and either don't go and don't do the homework, or, more commonly, I don't even realize I am supposed to be taking it. Once in a while the dream varies and it is some class other than math.
I never made the connection until now. It's not about math, or nudity. I don't have particular hangups about either. I suspect it has something to do with worrying about being caught unprepared.
I feel like my brain moves slowly sometimes, and I have forgotten a lot of what I learned in college or grad school. Perhaps this is the reason for the dreams. I felt it acutely last week at the conference, although it was more in my head than in reality.
