I had a very violent dream. Description explains it, Please EXPLAIN WHAT IT MEANS?

Okay so, I woke up this morning, and I had a truly violent and scary dream. I remember that I was out on my own (I'm only 15) and I think I fell. I felt my nose and it was bumpy. I felt it cracking and I guess it broke. I remember people were trying to help me and put a bandaid on it but I wanted to say "it's not gonna help, I think it's broken!" and it hurt to talk because my skin moved with my nose. And afterwards I remember my 2 year old nephew, my sister, my mother and I all in the car. We had a gun in the car for some reason (we usually don't in reality), and I remember the window was open and it somehow accidentally shot. It aimed for a store where the door was open and 2 overweight colored ladies sat. I yelled "duck!" and they looked at me and ducked. After that, they started cursing at me thinking I shot the fun, calling me "skinny a-- girl" "b----" and throwing f bombs at me. For some reason we had powers… So I got scared and teleported away and drank an invisible potion and turned invisible (probably a Minecraft thing that was) and I hid in the corner near the bed at home. My nephew came running in and hid next to me but didn't use any "powers". My sister and mother were still arguing with and fighting the 2 overweight colored ladies. And then I woke up. I felt my nose and it was fine. Thank God. So what does this all mean? I'm really confused… I don't have dreams as violent as this.
