I have a recurring dream where I'm back in either high school or college (I'm 31, and as of May 2022 it will have been a full decade since college graduation) and its almost time for final exams and I suddenly realize that I have a ton of studying to do because I don't understand any of the coursework. Usually it will be because I forgot I even had the course and never showed up for class, which is odd because in real life i never skipped class. I did have a lot of multi-day cramming sessions with very little sleep because I am a slow learner and barely passed a lot of classes in both HS and college despite putting in lots of effort.
This is actually the only dream I ever have. I used to dream about sex when I was younger, but that hasn't happened for years. These days I'm even an incel in my dreams.
What's weird is that even though that put me through a lot of stress 10 years ago, when I'm awake I usually think about getting bullied back in middle school but I never have dreams about that. I don't think that coursework traumatized me as much as bullies did so I'm not sure why the coursework is always what I dream about.
