Dream About Car Accident Family Chaos

I was shopping in a store browsing at clothes and food. I was with my family, two aunts, some cousins, and my grandmother. One of my aunts left and got in the car with my grandmother. I followed them outside and saw there was a cop yelling my aunt to put the car in park. She could control the gear shift and she accidentally stepped on the gas and the car went into reverse very fast. Me and my cousins were standing around stressed out. The car backed out all the way into the middle of the street and another car hit them. The person in the other car was honking them repeatedly but kept driving super fast and pushing my aunts car out onto the highway and the all the down the highway until they were out of our view.
