Altered State

An altered state of consciousness (ASC),[1] also called altered state of mind or mind alteration, is any condition which is significantly different from a normal waking state. By 1892, the expression was in use in relation to hypnosis[2] although an ongoing debate about hypnosis as an ASC based on modern definition exists. The next retrievable instance, by Dr Max Mailhouse from his 1904 presentation to conference,[3] however, is unequivocally identified as such, as it was in relation to epilepsy, and is still used today. In academia, the expression was used as early as 1966 by Arnold M. Ludwig[4] and brought into common usage from 1969 by Charles Tart.[5][6] It describes induced changes in one's mental state, almost always temporary. A synonymous phrase is "altered state of awareness". https://en.wikipedia.org/wiki/Altered_state_of_consciousness
