went to school for way too long and took school way too serious. I worked really hard in school and hardly ever missed classes and tests. School never really came that easy for me and I had to work really hard to do what others could do easily. So for me, I spent a lot more time studying than the average Joe. I think my mind subliminally knows that this is my worst nightmare and it likes playing with me every once in a while. Some people couldn't care less about school and so this dream would be nothing to them.
Oh and I'm probably a little psycho also.
