Freud dismissed Jung, who had been his heir-apparent, from his inner circle because of their differing ideas about the uncanny and Jung’s interest in the occult. Due to this rupture, many of Jung’s seminal ideas were lost to psychoanalysis. However, recent theoretical concepts in our field, including intersubjectivity and the intergenerational transmission of trauma, have led some psychoanalysts to reconsider the uncanny in their clinical work. Uncanny experiences are understood by Jungians as the central conduit to the unconscious. This paper will compare how the unconscious is conceptualized by Jungians and by Interpersonal and Relational psychoanalysts. Differing ideas about the unconscious are foundational to how the uncanny is now being understood in contemporary psychoanalysis generally and in Interpersonal and Relational Psychoanalysis in particular.
