Gas tanks are containers with a limited supply, and when they’re emptied, it really feels that there’s nothing left. So in our dreams, when we see a gas tank, it might represent the deep anxiety that we’re running out of something in life.
We can also interpret the dream as being about fuel. This could be interpreted as our need to refuel or recharge. We feel that all the energy and life we have is running out.
Some people believe that if you see your car’s gas tank in a dream, it means that you need to refuel your life with more positive energy and optimism. In other words, the car’s gas tank stands for our need for fresh enthusiasm, new ideas and creativity.
