Free association is therapeutically helpful in the regulation of states of consciousness. A person who free-associates enters a particular state of consciousness characterized by increased subjective self-awareness and disregard for reality, together with implicit pulls for objective self-awareness and reality adherence. Free association facilitates the patient' learning to integrate and to shift flexibly among points on these dimensions. Tensions existing in the free-associative state are embedded in a similar tension between free associating and reacting to the analyst' interventions, so interplay between free association and intervention also facilitates regulation of states of consciousness.
