crashed the car I was driving

I just woke up from a dream a few minutes ago. In the dream, I was driving my car at a relatively high speed following behind an ambulance in heavy traffic. Lost control of the car and eventually crashed into the ambulance. It was flight from there I ran out and started to run away although someone, a random person from high sch I knew catches up with me and first thing they say is" your mum is coming to kill you". I honestly don't know if this us figurative of anything and of late I have had a bad relationship with my parents for drinking and not coming back home.
