A battery symbolizes both power and energy. To dream of a battery running out of power suggests that there may be a health problem as yet unrecognized. As there are now so many different types of battery, ranging from tiny transistor types to large cells, the interpretation will vary somewhat. Largely, however, a battery is seen as a source of power. More mundanely, we may be having a problem in finding the energy to complete a project and need to find a different source of inspiration. In both men and womens dreams, since the principle is one of a balance of positive and negative, a battery can suggest the libido or the driving force.
