Disconnection appears in the depth-psychology corpus as a multidimensional construct operating simultaneously at somatic, relational, intrapsychic, and ontological registers. Its most persistent usage designates the severance of consciousness from bodily experience — a defensive operation triggered by overwhelming trauma that begins as an adaptive resource but calcifies, over time, into chronic estrangement from felt life. Levine, Ogden, and the NARM tradition of Heller treat this somatic dimension with particular precision, tracing how early attachment failures compel the infant to foreclose connection with body and social engagement before identity itself has consolidated. A second register, developed through the polyvagal framework of Porges and Dana, locates disconnection in the autonomic nervous system: when neural cues signal danger, the organism withdraws into protection through disconnection, converting a transient autonomic state into a habitual relational posture. Edinger, engaged by Dennett’s Jungian-astrological reading, introduces a psychospiritual dimension — disconnection between ego and Self generates alienation neurosis, a felt unworthiness bordering on the question of one’s right to exist, with psychic energy driven underground into depression, addiction, and primitive affect. Across these perspectives, a key tension obtains: whether disconnection is best understood as a deficit to be repaired through regulated bodily reconnection, or as a structuring condition whose resolution requires simultaneous somatic, relational, and symbolic work. The stakes are high — disconnection feeds psychosomatic symptoms, addiction, despair, and meaninglessness — making its clinical recognition a prerequisite for effective depth-psychological treatment.
