An altered state of consciousness may be defined as any state of consciousness that deviates from normal waking consciousness in terms of marked differences in the level of awareness, perception, memory, thought, emotion, behavior, and the way we experience time, place, and self-control.

Particular interest in the ways altered-state experiences may inform and transform ordinary, daily life.
