Going back to school

Recently I was attending a parents teachers conference at school, so this dream is not really that surprising. At least in the fact it happened, but what happened inside the dream is something else.

I was walking down the hall of the school towards the stairs up, my goal was the second floor. There really wasn't anyone around, except for few kids talking to each other. I begun to slowly walk up, since I didn't feel like I was in a rush, honestly I don't even know why was I there to begin with. I started scaling the railing of the stairs for no real reason and done some maneuvers that just aren't physically possible. When I finally got up someone told me that on the ground level my friend was hit in the face by an a guy not from the school. I rushed down and saw a small group of kids gathered around my friend, I immediately asked "Who did that?!" and all they did was just point in a direction.
I jumped that way almost in an animalistic fashion, even letting out a growl. I got to the stairs leading down to the changing rooms and grabbed a kid that was walking up. I yelled to him "Did you see anyone not from the school down there?" when he confirmed I run down, but was quikly stopped by a lady going up carrying benches, don't ask why, I have no clue.

At this point I woke up.
