Both the classical psychoanalysis of S. Freud, and the modern analytical psychology of C.G. Jung pays considerable attention to the manifestation of numerical symbolism in the structure of human consciousness and the unconscious. The psychoanalysis founders were interested in the direct manifestation of numerical symbolism in the person’s emotional experiences, his dreams, trance states. C.G. Jung discovered an interesting pattern: the symbols of the quaternary occur 71 times in a series of four hundred dreams and came to the conclusion that its manifestations are associated with the manifestation of the unconscious forces, while the trinity manifestation in the European’s dreams is more likely to relate to associations that have a rational and cultural origin.
