The shadow refers to the unconscious aspects of oneself that one rejects, including primitive or socially unacceptable urges and traits. It contains everything about oneself that one will not acknowledge. The shadow has two aspects - the less evolved and darker parts of one's psyche, as well as one's faults and weaknesses that are rejected by one's conscious ego. Failing to acknowledge and control the shadow through self-analysis can result in its manifestation in dreams combined with archetypes like the anima, representing one's shadow in projected form onto others. Integrating one's shadow through self-reflection is an important moral and psychological task.
