In general: The unconscious seems to sort information in which it draws comparisons and works out contrasts. In particular if the dreaming suffers from internal conflicts, he dreams in contrasts (possibly male / female, old / Jung, wisely / stupidly). The effect resembles that one internal pendulum which sorts the contrasts in a united whole. Psychologically: This juggling with contrasts can stretch a whole Time-long. Another dream in which he works on his female side can follow a dream in which the male side of the dreaming is cleared. With the interpretation of dreams bigger examination into the spiritual processes becomes possible if the dreaming looks at the respective opposite of dream figures, dream situations and moods. Spiritually: At this level contrasts stand in the dream for the attempt to attain a spiritual balance.
