Once he had set up in private practice back in Vienna in 1886, Freud began using hypnosis in his clinical work. He adopted the approach of his friend and collaborator, Josef Breuer, in a type of hypnosis which was different from the French methods he had studied, in that it did not use suggestion. The treatment of one particular patient of Breuer's proved to be transformative for Freud's clinical practice. Described as Anna O., she was invited to talk about her symptoms while under hypnosis (she would coin the phrase "talking cure" for her treatment). In the course of talking in this way, her symptoms became reduced in severity as she retrieved memories of traumatic incidents associated with their onset.
