Money typically represents something the dreamer values. It can also represent the dreamer's energy, potential or abilities. Money can also be a symbol for power, the ability to change things or having power over someone else.
Sometimes dreams about money can also be about personal potency and sexuality. Money might also indicate an opportunity for the dreamer.
Finding money in a dream can be a metaphor for realizing how valuable something is. It might also represent a release from stress or a gain in power.
Losing money in a dream can mean the dreamer feels like he or she is losing power. Not having enough money can symbolize inadequacy. And stolen money might mean the dreamer is feeling guilty about gaining power or is feeling cheated by a loss of power.
