We were going on some sort of ecology field trip in a school bus when my science teacher started backing up onto the football field. He said something along the lines of "It's their problem".
Then I remember seeing a splatter of blood go past my window, so I look back and the entire football team has been run over, gore is everywhere (meaning organs too), it's a bloody mess, and some people have been dismembered.
I woke myself up but if I closed my eyes I could still see the scene. It was messed up.
