DATE: Sometime early in 2023, distinctly before "Spanish Teacher" dream

I entered my Algebra 3/Trig class into a lecture hall (unlike in reality) and I made some talk with my teacher and I ended up talking about some of the hardcore idm I was into. He said something "oh yeah I like that stuff too." He then pulled up some of his albums and showed them to the class. All of the album covers were just writings of formulas with the titles being names of mathematical concepts written out in a plain grotesk font, along with his full name and title. He showed us the songs, and they were borderline noise and I loved it. After that, we continued class as normal.
