Carl Jung associated the moon with the feminine principle, the anima, and the unconscious. In Jungian dream analysis, the moon represents that which is hidden, cyclical, and connected to deeper wisdom beyond rational thought. Jung noted that the moon reflects the light of the sun (consciousness) into the darkness, symbolizing how intuition illuminates what reason cannot reach. Moon dreams often appear when the dreamer needs to trust intuitive knowledge or pay attention to the feminine, receptive aspects of the psyche.
