What does my dream mean?

I had this dream where my mother and cousin and grandmother were in the car with me while i was driving. The drivers door wouldnt stay shut and the breaks wouldnt work. I was speeding and i was a horrible driver when im not in real life. Then we stopped somehow at my cousins houses but i didnt want to go in so i stayed on the porch. Then a guy in an old VW van drove up and pulled out a gun and started shooting like a drive by. I was on the ground and didnt get hurt and the party going on in the house kept going. What do u think all this means?
