A psychosomatic model of dissociation is proposed that addresses the ever adjusting mind-body relation—the constant titration of the quality and degree of the psyche's embeddedness in the sensorial and temporal life of the body. The model highlights the function of hypnoid mechanisms (autohypnosis, distraction, somatic autostimulation) and of altered states of consciousness in facilitating and masking the work of mind-body dissociation. Transient altered states, which enable new and creative forms of mind-body experience in everyday life and in the therapy situation, are contrasted with pathological forms of retreat into alter worlds—rigidly organized, timeless, often inescapable trancelike states of mind-body dislocation. These pathological dissociative structures reshape the life of the mind and of the body, requiring new clinical approaches to these phenomena.
