seen by Moreno to simply be positive side-effects. A poem by Moreno reveals ideas central to the practice of psychodrama, and describes the purpose of mirroring: In 1912, Moreno attended one of Sigmund Freud's lectures. In his autobiography, he recalled the experience: "As the students filed out, he singled me out from the crowd and asked me what I was doing. I responded, 'Well, Dr. Freud, I start where you leave off. You meet people in the artificial setting of your office. I meet them on the street and in their homes, in their natural surroundings. You analyze their dreams. I give them the courage to dream again. You analyze and tear them apart. I let them act out their conflicting roles and help them to put the parts back together again.'" While a student at the University of Vienna in 1913–14, Moreno gathered a group of prostitutes as a way of discussing the social stigma and other problems they faced, starting what might be called the first "support group". From experiences like that, and as inspired by psychoanalysts such as Wilhelm Reich and Freud, Moreno began to develop psychodrama. After moving to the United States in 1925, Moreno introduced his work with psychodrama to American psychologists. He began this work with children, and then eventually moved on to large group psychodrama sessions that he held at Impromptu Group Theatre at Carnegie Hall. These sessions established Moreno's name, not only in psychological circles, but also among non-psychologists. Moreno continued to teach his method of psychodrama, leading sessions until his death in 1974. From 1980, Hans-Werner Gessmann developed the Humanistic Psychodrama (HPD) at the Bergerhausen Psychotherapeutic Institute in Duisburg, Germany. It is based on the human image of humanistic psychology <ref>Gessmann Hans-Werner. Die Humanistische Psychologie und das Humanistische Psychodrama. In: Humanistisches Psychodrama. Band IV, Verlag des Psychotherapeutischen Instituts Bergerhausen, Duisburg 1996, .</ref> All rules and methods follow the axioms of humanistic psychology. The HPD sees itself as development-oriented psychotherapy and has completely moved away from the psychoanalytic catharsist theory. Self-awareness and self-actualization are essential aspects in the therapeutic process. Subjective experiences, feelings and thoughts and one's own experiences are the starting point for a change or reorientation in experience and behavior towards more self-acceptance and satisfaction. The examination of the biography of the individual is closely related to the sociometry of the group. Another important practitioner in the field of psychodrama
