I dreamt that I was both teaching and studying at the same university. I remember being concerned about likely conflicts in my two schedules. At some point I was rushing to a lecture that was to start in a quarter of an hour without being sure whether I was to act as a teacher or as a student. In fact, I was not prepared for either. When I woke up, I was at first struck by the strange conflation of my duties in my dream. It took me an hour or so to remember that I was indeed both teaching and studying at MIT while I was working on my doctoral thesis. Although there were no overlaps of the two schedules, there was nothing strange about the conflation of my duties. It took me another few hours to realize that the conundrum comes from the fact that all this took place nearly forty years ago. I am starting to forget about my doctoral studies, that is.
