I am Dango, Hear Me Roar

This was a worrisome dream. I was at some event at school. I think it was a concert that had just ended. I was heading out past a stage with a band just playing for the people left over. As i get closer to the gate out, I start to run. Just as I pass some guy, he drops a flyer of some sort and I accidentally step on it. The guy cusses me out as I run past and I apologize, but he keeps cussing. I just keep running but hit an intersection. As I try to cross, a big truck comes by and nearly hits me. I hear some yelling from behind me and discover it's the guy from earlier, still mad at me. He comes up to me, still screaming "really? Why didn't you pick up the wedding flyer? Why did you step on it?" And I apologize again, but he gets more and more threatening and starts to insult me. I get so mad I throw a fake punch to try to scare him. He just keeps going and I get so angry that I strangle him. I started to choke him and as I was about to punch him after he passed out, I woke up, still shaking with anger
