I Just Can't Focus in Class Anymore

So, lately I've been having trouble paying attention during lectures. It's not like I didn't care before, but now my mind is just constantly wandering to all these random thoughts and ideas. Like right now, I'm supposed to be listening about the history of algebra, but instead, I'm thinking about how cool it would be if algebra could actually solve real-world problems instantly, kind of like a magic calculator. That would really change things in life, wouldn't it? But then my mind jumps to something else entirely - you know that time we decided to prank the entire dorm by leaving fake notes saying there was free pizza downstairs after midnight? Yeah, turns out we got pranked right back and found out there actually WAS a secret delivery of pizza. It was hilarious but also kinda embarrassing because I ate three slices before realizing they might be trying to mess with us. Back to algebra! Or am I still thinking about that prank? Maybe both? Anyway, anyone else having trouble focusing these days?
