A need to relax, or rest from the things that 'drive you'. Because there were a lot of other cars and it was unplowed, suggests you feel your life is busy, if not cluttered, lately.

If you are hiding out of danger, then you should consider those things in your life that you feel propose a threat to you. They could be internal forces or environmental conditions. Generally, we attempt to hide our own negativity and mistakes. This dream may call for an honest reflection on personal characteristics and an evaluation of how much fear influences our lives and decision-making.

Gun - Dreaming about guns and interpreting these dreams depends greatly on your attitude about guns. Many people are uncomfortable with the life-and-death power of guns. If you don't like guns, or are afraid of the gun's power, it is a taboo symbol.

The gun may represent a nearly desperate need to reassert personal control in the situation or to find personal power in relationship to others.
If the gun in the dream is used to hurt or kill you or someone else, please consider your current difficulties, hostile feelings or serious arguments, which you may have within yourself or with others.

Shooting/Shot - a fearful and violent dream experience. It may reflect aggression, powerlessness, release of strong and dangerous emotions, and/or symbolize a conclusive event in a particular situation or relationship.
