@cypnk i failed a grade in middle school, and one of my standard nightmares thereafter was that i had been held back again.
in adulthood, this transformed into a recurring dream that i had through some inscrutable process been recalled as an adult back to some strata of k-12 education because i didn't _really_ graduate. usually with a side of not remembering my locker number.
it's mostly fallen off in my late 30s, thank god.
