Freud called dreams the royal road to the unconscious. Sigmund Freud was an Austrian psychiatrist who established the psychoanalytic school of psychology. Freud developed theories of the unconscious mind and the defense mechanism of repression. He created the clinical practice of psychoanalysis for curing psychopathology through dialogue between a patient and a psychoanalyst. Freud used the interpretation of dreams as a means of discovering insight into unconscious desires. Delusion And Dream is Freud's interpretation of the vel Gradiva by Wilhelm Jensen. A gradiva is one who walks. Gradiva was a fourth century BCE sculpture of a robed woman who lifts the hems of her skirts to stride forward. Gradiva is a story of a young archaeologist who suffered a mental disturbance and was gradually cured by a kind of native psychotherapeutic instinct. Delusion And Dream began the practice of using psychoanalysis in literary criticism.
