Recurring Nightmare

I have this recurring nightmare that it’s close to graduation time from high school, and I suddenly discover that I don’t have enough gym class credits to graduate. So I start to panic, what am I going to tell my parents? “Oh sorry, looks like I won’t be graduating from high school because I skipped a couple of gym classes!” I mean seriously, within the parameters of my dream, that means that I’ll have to go back to high school in the fall with all the people who were below me previously! And then I wake up and thank the heavens that the dream was only a dream, and then I fall back asleep, only to have it again.
