curious re dream

I'm in my parents car with my mom driving and my immediate family in the back seat, I don't remember who but I know they were there. I think my oldest brother and my dad might have been driving in my brothers car beside us. We come to a corner where my mom needs to turn right but she won't, the cars are honiking behind us and people are yelling. I keep telling my mom to go but she won't. Then we're out of the car and there are police across the street blocking off access to the road. They're in riot gear. We go to the sidewalk with the rest of the crowd and the police start to shoot at a house. The shooting stops and a man comes out. He lifts up a gun and starts shooting in our direction. We scream and drop to the ground. I think I pulled my brother down on top of me.
