Altered state of consciousness

Altered state of consciousness is a phrase, coined in the Seventies, to describe intentionally induced changes in one's mental state, sometimes through the ingestion of drugs and psychedelic substances such as LSD, peyote, marijuana, mescaline, and the like.

An altered state of consciousness can also be attained from alcohol, a sensory deprivation[?] tank, hypnosis, and the practice of certain rituals (e.g. prayer) and disciplines (e.g. yoga).

Naturally occuring altered states of consciousness include channeling, dreams, premonitions[?], and euphoria.
