A Dictionary of Dream Symbols
by Eric Ackroyd(2) The hero may symbolize your conscious ego. Just as in myth the hero ventures into strange lands and wrestles with monsters to take possession of some great treasure, so the conscious ego must venture into the unknown realms of the psyche and face up to, tame and use creatively the forces that lie in the unconscious.
(3) If the hero rescues a maiden, the meaning - for a male dreamer - will probably be that he needs to bring the feminine side of his nature into active collaboration with his masculine side.

(4) If in a man’s dream the hero is assisted by a young woman, the hero may symbolize the conscious ego and the young woman the anima. The lesson will be as in (3) above.
(5) If the hero is accompanied by an older person (or friendly strong animal), that person / animal may represent innate wisdom and power in your unconscious: that which, from within your own psyche, can supply all that your conscious ego needs.
