Copying a blank Test in a circular Classroom

"I was back in school taking some test, but it wasn't a real class I recognized, and the desks were arranged in a circle which no classroom ever does. I was completely unprepared. The questions weren't even questions, just blank pages with like one word at the top, and everyone around me was writing furiously like they knew what to do. Then I realized I could see the smart kid's paper from where I sat, and I just... started copying. No guilt about it at first, just relief. I was copying fast, hand cramping, and I kept thinking "just this once" even though I had no reason to even care about this fake test. I didn't even want to be there. I don't know why passing felt so important, but it did, like my whole life depended on a test in a class I never attended. At some point the teacher, who was my old math teacher but also somehow my dentist, walked behind me and I felt the paper crinkle under my arm where I was hiding the copied answers. She didn't say anything. She just looked at me, and I couldn't read her face, and she kept walking. That was worse than if she'd yelled. Then I was in the hallway and my best friend from high school was there asking me why I did it, and I kept saying "I didn't even need to" which was true, which made no sense, which made me start crying in the dream. I wasn't crying because I got caught. I was crying because I couldn't explain my own reason for doing it. I woke up feeling genuinely guilty, like I had to remind myself I haven't taken a test in years. Checked my phone to make sure I didn't actually miss anything important. Brains are exhausting."
