This study analyzes the reinterpretation of Freud’s psychology theory related to Terry Johnson’s play Hysteria. It processes characteristics in Freud’s unconscious with the motif an encounter between Freud, the psychoanalyst and the surrealist, Dalí. The characters in this play all symbolize parts of the unconscious, thereby revealing Freud’s inner world is related to each character. Jessica symbolizes the “id,” Dalí the “ego”, and Yahuda the “superego”. This paper reveals that the underlying unconscious represented by the characters is caused by Freud’s suppressed trauma. Freud has two traumas. One is guilt for the suicide of his former patient, Jessica’s mother, following Freud’s faulty counseling. The second trauma relates to his guilt of leaving his sister in Vienna when he escapes from Nazi Germany. This study contrasts Freud’s suppressed identity with Dali’s expressed idea, revealing the relationship between Freud’s suppressed trauma and Dalí’s surrealist representation. At the end of the play, Dali appears and causes the realization that Jessica signifies Freud’s trauma. Freud, who is trapped in his unconscious, realizes and reconciles with his traumas. Johnson uses this dramatic representation of psycholanalysis as an opportunity to look back on old Freud’s life. Although the theme of Hysteria is the rather dark and serious unconscious, Johnson redefines hysteria along with the issues of Freud's unconscious. In this way, Hysteria takes a look back at Freud’s life. This study revisited Freud through Dalí and the characters.
