Dream About Car Driving On Its Own

I had a dream where I fell asleep in the car and I woke up and my mom and brother left so I waited because I figured they be back to come get me, it looked like I was in the parking lot of an apartment complex and I started getting nervous because no one had came to get me, then the car started driving in its own and it turned out of the complex. I stayed calm because I was sure someone would help me and as the car was driving on the road really fast I was kind of leaning out the door screaming for help, then the car started running people over and there was a bunch of car crashes and fire and people were really injured and some were even on fire. I was finally able to get out of the car because I suddenly realized I could've just opened the door. Then I ran out to check on the people and I told them to let me go get my stuff and I'll come back to help them walk and so I went and got my stuff and I asked the people why they were by a car that was dangerous instead of running away and it was a couple I was talking to and they said it was because one just found out the other cheated and I agreed that that wasn't right and then I helped them go get help and woke up
