Der Wahn und die Träume in W. Jensens Gradiva (Delusion and Dream in Jensen's Gradiva) is an essay written in 1907. It is a psychoanalytic interpretation of a work of fiction (Gradiva by Wilhelm Jensen.) The novel tells the story of a young archaeologist, Norbert Hanold, who comes to realize his love for his childhood friend through a long and complex process, mainly by associating her with an idealized woman in the form of the Gradiva bas-relief.
Freud considered the novel as providing a prime example of something which might be called "cure by seduction" or "cure by love", as well as evidence that the Oedipus complex is still active in normal adults. There has been numerous references to and comments on Freud's original interpretations from both psychoanalytic and other circles.
