Nineteenth-century writers such as Robert Louis Stevenson in “The Strange Case of Dr. Jekyll and Mr. Hyde” struggled with dream material and duality in man. Freud, conceptualizing psychoanalysis in this milieu, was enormously influenced by literary writers, who he believed were in tune with the unconscious. Through Freud's Interpretation of Dreams and Stevenson's novella, the link between an author's unconscious and his written work is explored.
