Altered States of Consciousness

A large and scattered body of clinical and research reports on daydreaming, sleep and dreams, hypnosis, sensory deprivation, dissociative and depersonalization states, and drug-induced mental changes has not been organized into a consistent theoretical framework. This work aims to integrate current knowledge about various altered states of consciousness to determine the conditions necessary for their emergence, the factors influencing their outward manifestations, their common denominators, and the adaptive or maladaptive functions they may serve.

Abstract

BENEATH man's thin veneer of consciousness lies a relatively uncharted realm of mental activity, the nature and function of which have been neither systematically explored nor adequately conceptualized. Despite numerous clinical and research reports on daydreaming, sleep and dream states, hypnosis, sensory deprivation, hysterical states of dissociation and depersonalization, pharmacologically induced mental aberrations, and so on, there has been little attempt made to organize this scattered information into a consistent theoretical system. It is my present intention to integrate and discuss current knowledge regarding various altered states of consciousness in an effort to determine (a) the conditions necessary for their emergence, (b) the factors which influence their outward manifestations, (c) their relatedness and/or common denominators, and (d) the adaptive or maladaptive functions which these states may serve for man. For the purpose of discussion, I shall regard "altered state(s) of consciousness" [hereafter referred
