This was when I was in elementary school.
      Basically sonic was at the school and he was evil. No one except for me could be in the same room as him. I was faster than him. We were placing signs around claiming the parts of the school. I was tge only one out of us two who could replace his signs with my signs. The places I remember us mostly focusing on were the cafeteria and the playground. This was a reoccuring dream.
