Letting things go

Friday night dream... Dorothy and I are standing on a hill next to our dark blue 2008 Nissan Sentra. The car starts rolling down the hill towards a highway full of traffic. I try to chase after the car but Dorothy holds me back smiling and laughing. I'm furious. I want to save the car and she won't let me go. The car reaches the road and makes a right hand turn by itself and disappears.
