Dream About Cannons And Trippy Patterns

I was with a group of people in a classroom setting and I remembered getting very upset. I think i was picking up a child or something. I started talking to a child in the class about something but i think her mom didnt like that after seeing me getting upset and going off on the teacher or something. After a little while I was all of a sudden and part of the class and I was in the middle back of the class. The teacher was talking and I was raiding my hand to answer. I answered one question but I could tell he didn't want to call on me after the outburst. I then started to see trippy patterns everywhere moving around like I was on psilocybin or something. I told the classmates next to me what I was seeing. Shortly after we went outside. We were on a small hillside and there was dried grass and a asphalt road we were walking that lead to a main neighborhood road. We then were deeper in the neighborhood subdivision and my classmates noticed a small cannon like a pirate cannon on a ship. It was at the top of the street. They rolled it to where we were and one of the guys shot it off. The cannon ball flew into the air and back down smashing into a house it ended up hitting a guy and his dogs and cats. The animals appeared okay but the man seemed a little confused. I called 911 since nobody else was doing so and told them what had happened. I was talking like I used to when working on an ambulance. Saying stuff like male in their late 40s approximately 220lbs, etc. I think at one point in the dream i did the reality check and became aware but that may have been a different dream as i do not recall being aware in this dream.
