From the earliest times, machines were compared with the human body; therefore, when one appears in dreams, it may be referring to your physical well-being, especially if the machine malfunctions, is broken, or needs some kind of maintenance or repair. Therefore, if you dream of machines, you can interpret these images as a report of the state of your body and mind. The way they work will let you know how your health is. The fuel of the machine can symbolize your sexual energy or power. If the dreamer is driving the machine, it probably alludes to their ability to function in life and deal with problems. The meaning of each machine depends on the elements that compose it and the pace at which it moves.
