Pluto or Hades are synonymous with hell. Pluto is the brother of Zeus and Poseidon and the ruler of the underworld, or the land of the dead.
The kingdom of the dead is located underneath the surface of the earth. It is not only the holding place for the eternally damned, but is symbolic of metamorphoses, mineral wealth, germination and the transition from death to life. From a psychoanalytic point of view, Pluto may represent the deepest and the oldest part of the psyche. It may be the holding place of the darkest and most negative and disturbing elements of the individual.
The most destructive emotions and the greatest fears may be hidden there. However, this dark part of the psyche may also hold the greatest amount of transformative energy and power. As the unconscious demons begin to surface and are processed and then assimilated by the conscious mind, the individual begins to develop and experience feelings of completeness and wholeness. Astrologically, Pluto is symbolic of radical reconstruction that rejects harmful elements and is built on a solid foundation. Seeing Pluto in dreams seems to be an extremely valuable message from the unconscious. It suggests that the dreamer needs to contemplate and to explore his inner world; to face his fears and negative traits, to travel inward and then to emerge stronger and more alive than before the psychic or soulful journey began.
