The Great Father is the symbol of an aware and elevated consciousness. You are standing with great awareness in the world. In fairy tales, as well as in dreams, the self usually has a royal beginning, from which it is separated in order for it to master the adventures in the world.
The king also means wholeness and completeness.
The Great Mother is symbolized in the dream as a queen, always representing the image of wholeness. In the end she represents the integrating power of nature. Furthermore, the image of the queen as the fertile mother always addresses the self of the dreamer. Implied here is the idea that we should rely on our own abilities, care for ourselves, and find a Home within ourselves.
Kings and queens also represent one’s masculinity (animus) and femininity (anima). Such archetypes are not only persons of authority, but they also represent the image of a loved one (idealized and elevated masculinity or femininity). According to Freud, often the symbol of parents who are seen as overly powerful.
