The shadow is the unacceptable or unknown aspect of ourselves. It derives from our pre-human, animal past, when our concerns were limited to survival and reproduction, and when we weren’t self- conscious.
Symbols of the shadow include the snake, the dragon, monsters, and demons. It can appear in many different dream disguises: a foreigner, gypsy, tramp, prostitute, murderer, thief, stranger, alcoholic, drug addict, rapist, burglar, crippled, deformed, blind, a servant or someone following you. It often guards the entrance to a cave or a pool of water, which is the collective unconscious.
The shadow is not always represented as an enemy in dreams. It often contains values that are needed by consciousness and only becomes hostile when ignored or misunderstood. Although it suggests the ‘dark side’ of the ego, the shadow is actually amoral—neither good nor bad, just like animals. An animal is capable of tender care for its young and vicious killing for food, but it doesn’t choose to do either. It just does what it does. It is ‘innocent’. But from our human perspective, the animal world looks rather brutal, inhuman, so the shadow becomes the part of ourselves that we can’t quite admit to.
