Another nightmare about going back to high school

Dammit, another dream about not finishing high school 

And I missed the first day of class so I started falling behind on… advanced multivariable calculus??? Since I already finished the multivariable calculus series 

And it's a high school, so this teacher is too dumb and unqualified to teach calculus, just like when Mr R——- was teaching AP Calculus in 11th grade 

And for some reason the high school had to do bionic surgery on my hand in order to attend, so they put bungee cord into my hand to clot the surgery.

But then the bungee cord fell out and now I had a "dry socket" akin to the painful complication after wisdom teeth extraction 

And the high school students kept coming up to me but I didn't have the heart to tell them uh I am not a high school student
