This chapter attempts to convey a self-psychological approach to trauma and dissociation in the context of a clinical case. It explores own subjectivity and understanding of the patient's subjectivity and the "us" in various moments of the treatment. The chapter attempts to track dissociative parts of both therapist and patient. It also attempts to elucidate some of the ways Self Psychology contributes to new relational paradigm thinking and also leads to current theories of trauma and dissociation. In the 1950s Heinz Kohut, the founder of Self Psychology, joined the growing trend in psychoanalysis in asserting that psychopathology originates in the child/caretaker unit and the resulting derailment of the child's ongoing development. Kohut's concept of empathy has been expanded from a unidirectional process to a mutual interactive attunement. Stolorow's intersubjectivity is an epistemological construct, assuming the indissoluble unity of two subjectivities in a dyadic system whether or not they are conscious and articulated.
