I keep dreaming about school

I dropped out of college over a decade ago, but the dreams constantly keep happening. I feel like it comes down to some anxieties I have about my intelligence, my ability, and past failures.

Some of the more notable dreams of this subject involve me, a 32-year-old man, attending grade school classes for some prerequisite I failed to collect years prior. My most recent dream involved me failing out of second grade math, with my teacher just staring at me pityingly.

Anyway, I assume these are fairly common experiences for most people. Most of them involve me trying to find my class, only to realize that I am, in fact, not in school at all anymore.
