I’m not sure what it means but I’ve never had the naked or near naked uncomfortable dream, but I do have the showing up to class and discovering it’s the final or midterm and I have no idea about the topic. A similar one is trying to find said classroom. No one helps me in my dream either. Very rude of these dream entities. The other version for me is from my waitressing bartending days (a long time ago). I end up with 100’s of tables and just running between them all with angry patrons demanding this and that which I can’t seem to get. I’m happy to report that these anxiety dreams have pretty much stopped since retiring. Go figure!
