Recurring dreams about being lost and back in high school?

Al

I graduated in 2013. lately Ive been having dreams about being in high school again, and in a lot of them Ive somehow lost my class schedule or cant read it and can't find my classes, so I'm panicking and trying to find another copy of my schedule but I cant find the office, cant find a teacher, etc. I did just start college again (online) after taking a year and a half break, so maybe that has something to do with it?
