Dreaming of going home by car indicates that you are moving towards a stable life.
Suddenly coming to a strange environment or a very strange natural scenery shows that you are nervous or afraid of the strange environment in your life.
Resistance shows that you have a solution to the unfamiliar environment, which can be said to be independent.
Things left in the car, still can't hide the inner fear. It can be said that you accidentally left something important behind.
