"Delusion and Dream: an Interpretation in the Light of Psychoanalysis of…" by Sigmund Freud is an essay written in 1907 that applies psychoanalysis to Wilhelm Jensen's novel Gradiva. Freud examines how a young archaeologist, Norbert Hanold, unconsciously transforms his repressed childhood love into an obsession with a woman depicted in an ancient Roman bas-relief. Through delusion and dreams set in Pompeii, Hanold eventually confronts reality when his forgotten sweetheart cleverly guides him back to sanity, demonstrating what Freud called "cure by love."
