This article explored the idea of a relational unconscious, which presumes three interconnected ideas about human interaction. First, meaning and understanding are coconstructed and intersubjective and not universal, absolute, and preformed. Second, there is a fluid boundary between conscious and unconscious experience that is intersubjectively mediated. Third, language is basic to human experience, whether or not a particular experience can be verbally expressed. This view of unconscious experience suggests that a therapist's participation is a major determining influence on the generation, awareness, and expression of a patient's unconscious experience. In applying a relational view of unconscious processes, self-disclosure is used to consider the usefulness of therapeutic interventions, to think critically about the nature of human interaction, and to specify how the therapeutic relationship promotes healing and growth.
