I haven't had the forgot-to-study-for-an-exam dream in a while. I just had a new version of that dream: I had to teach a college class and had completely forgotten about it, didn't even seen the textbook, didn't know where the classroom was, and when I made it there in the nick of time, there were two other instructors in the audience to evaluate my first lecture of the semester.

Thanks brain 👍 , going back to bed now.
