Engine – An engine of a car symbolizes the energy and power with which you move toward your goals. If your engine is failing in your dream, this indicates a loss of motivation or empowerment. If you are able to repair your engine, this signifies confidence on your part that you are able to take the steps you need to in order to begin moving toward your goals again. If you have built an engine, it indicates confidence in your engineering and problem-solving abilities, as well as your ability to self-direct and create your own destiny. This is a very beneficial symbol.
