This paper’s aim is to examine the points where autobiographical documentary theatre and emotional model in dramatherapy can be shared by analyzing autobiographical documentary theatre as an example of emotional model in dramatherapy, focussing on The Three Elements of Theatre. Research on the correlation between autobiographical performances, documentary plays, and drama therapists can be productive from a perspective of applied theater. Theatrical performances based on personal life, documented archives, and the past trauma of the individual promote the theatrical practice, social utility, community formation, and the theatre-making drama related to education. From this point of view, it is meaningful that the identification of the healing attributes inherent in the autobiographical documentary drama, such as The Three Elements of Drama, is capable of confirming the broad effects of drama therapy. In The Three Elements of Drama, the stage of dramatic projection is deliberately visualized through reciting the monologue of the opponent. I in you is realized, and it is expanded to the whole performance through the embodied aspect such as mirror play. In the projective stage where my feelings are confirmed through you, there is a chance for Yeong-min and Soo-yeon to integrate with their respective self by the coexistence of sorrow, anger, self –hatred and comfort, happiness. Beyond the middle of the play, attempts are being made to dismantle existing cultural divisions that divide persons with disabilities, non-disabled persons, and their places into places of abnormality and normality. At this time, the individual and impure feelings of Young-min and Soo-yeon sublimate into universal, pure, selfless holy anger that resists cultural dichotomy. The aspect of the emotional development that is terminated by pure holy anger is helpful for the self - awareness of the actors and the audience.
