Cars are the way in which we travel towards our goals. The car is largely a symbol of day to day reality in our conscious world. Its about our real life projects and achievements rather than the emotional goals and feelings. A parked car will generally symbolise one of two things. You are just about to start a new project or move off in some new direction. Or you have ground to a halt because of some problem. Think about your real life and the problems in it. Parking a car may suggest that you are trying to move towards a new and more conmfortable situation. Maybe you are wanting to let things settle down after some disruptions in relationships.
