Another data point, this time from a retired university faculty dude. I have recurring dreams of having to give a lecture (typically at a graduate physics level, which is what I taught most) but have not prepared. Worse--I'm not sure where the lecture room is. Sometimes I dream about winging it--and wake up mildly proud that I remembered as much as I did, though it was wrong in detail.
