Mary & Her Mean / Rude Mom & High School Graduation Again

I woke up almost forgetting all of my dreams from last night like maybe I slept too deeply for too long or something like that, so I woke up with a blank mind mostly not even knowing what day it was at first, and I barely remember part of my last dream.

The dream took place during the day in a fictional place, and I was in a fictional dimly lit school auditorium, and I was in high school again with fictional and maybe real former classmates, and we were going to have our high school graduation inside the auditorium later in the day during the evening or night probably; and so we were somewhat practicing for the graduation I guess and some of our family/parents/et cetera and teachers were there as well.
