Depth psychology is a branch of psychology that focuses on the unconscious mind and its influence on human behavior. It explores the underlying motives, desires, and conflicts that shape our thoughts and actions. This approach often involves examining dreams, fantasies, and symbols to uncover hidden aspects of the psyche. Key figures in depth psychology include Sigmund Freud, who introduced concepts like the id, ego, and superego, and Carl Jung, who emphasized the importance of archetypes and the collective unconscious. Depth psychology aims to provide a deeper understanding of mental processes and promote personal growth through self-awareness.
