The foundational experiences of Carl Jung's psychoanalysis include his studies of the unconscious mind and personal experiences with psychology. His early fascination with dreams and myths led him to explore archetypes and the collective unconscious, concepts that became central to his theories. The impact of his relationship with Sigmund Freud also shaped his thinking, ultimately leading him to diverge from Freud's ideas and establish his own psychological framework. Jung's emphasis on individuation, spirituality, and the integration of opposites continues to influence contemporary psychology and self-understanding.
