Deep Inside The Lucid Dreamer's Subconscious

In the dream I'm in a huge room in some sort of factory or school. There are desks leading up to a chalkboard and the ceiling is very high up. I'm taking a final exam and I'm the last one to finish. Everyone else is walking away like they're finished. There's a metal structure at the back of the class. People are on the other side with the professor going over the exam. I was walking up to the teacher when I overheard her discussing answers. I started copying down the answer. At some point she was going over a question and said it could be true or false she'd give credit to anyone. I wrote something down. I went back to my desk and people started coming over to me surprised I wasn't done. I unfold the test into this massive 5 by 8 piece of paper with the exam pages spread out.

I had another dream I was at the pool lifeguarding but I can't remember anything beyond that.
