Vehicles in dreams represent a calling or vocation, a 'conduit' or 'means' by which we get from where we are--to where we are going. A car may represent our job or particular life activity, a plane may indicate a large group that is spiritual in nature or that is 'going to far places'. For different types of transportation, take note of their function, color, speed, age, and other details that may direct our understanding.
Multiple vehicles dream:
I dreamed I started a new job. I was in the passenger side of an ambulance. We were just driving down the road, fast but not too much in a hurry. Suddenly, from behind us on the right, a fire truck came up. It had its sirens on and was moving really fast. It looked more like a monorail train, bright, sleek, red all over. As soon as it caught up to us, our driver put on our siren and we sped up. The train passed us and the force of air caused us to fly. The doors fell off and we became like a helicopter. I prayed I wouldn't fall out and told the driver I didn't have my seatbelt on. He said to buckle up. I was trying balance and do it without falling out.
Interpretation:
You are part of a versatile organization that brings healing to others. While you are headed in the right direction, a sudden spiritual movement or force gives you the power or drive to step up the pace in moving forward. This requires transformation and skill on your part to focus and keep 'balanced' so that you can stay 'on track' and 'take off' rapidly in your calling, which you are equipped to do even if you don't quite feel ready to handle it all. You are shown that you have guidance and support for this part of your journey.
