DAE still dream they forgot they were enrolled in a class and never turned anything in, even after graduating?

It’s been nearly a decade since I graduated from university, but about once a month I still have the same kind of stress dream.

I suddenly realize I was enrolled in a class I completely forgot about, and the whole semester has already gone by. I haven’t shown up, I haven’t submitted a single assignment, and it’s too late to do anything about it.

That hasn't happened to me even a single time, and yet I keep dreaming about this scenario.
