Among the works of Freud, he was most famous for his developmental theory of Psychoanalysis. Freud delved to the understanding and treatment of psychological disorders where he and his friend Josef Breuer discovered the “talking cure” after making a patient suffering from hysteria named Anna O to talk about her traumatic experiences which eventually led to a more developed form of therapy called “free association”. This contributed to the birth of psychoanalysis. Psychoanalysis assumes that the unconscious mind is the most powerful force behind thought and behavior and that dreams have meaning and are the most direct route to the unconscious mind arguing that the conflicting impulses, thoughts, and feelings that threaten the waking mind are released as visual compromise in distorted and disguised form by the sleeping mind. It also assumes that our childhood experiences are a form of a powerful drive in the development of our adult personality and that sexual and aggressive impulsion and the repression thereto are part of the maladaptive behavior of adults.
