They'd be pretty wierded out too. I've been out of high school for 5 years now and I dreamt that I was back.
For some reason this dream was a continuation of one I had like 6 months ago. I walked into math class and told the teacher I wasn't in class yesterday (when I last had the dream I skipped class). She then passed out tests and I honestly have no idea what the hell kind of math this was. There was a number and then standing on it's side right next to the number was two pi symbols, one on top of the other. What the fuck am I supposed to do with that?
Well my teacher comes up and says really loud, "YOU DIDN'T DO YOU TEST!" And I replied, annoyed, "I didn't do it because SUCK IIIIIIIIIIIIIIIIIIIIIT!" And then I found a cell phone on my desk that called a general in the Royal Air Force (I'm American...) and he threatened to kill me. ¯\(º_o)/¯
