Means "mind manifesting." It is used to describe the state of consciousness typically experienced while under drugs such as LSD, mushrooms, mescaline and cannabis - consisting of various stages of ego-release and an often startling alteration of perceptions.

This word is also applied to the writings, art, movies and music that are inspired by or that enhance the psychedelic experience.

The term was coined by psychiatrist Humphrey Osmond, MD who was disatisfied with the old term used to describe the experience "psychomimetic" which alluded to the experience replicating psychosis.

A more formal term originally used to describe something that seems inspired by a mind-altering drug, or the effects of the drug itself. Drugs classified as "psychedelic" include marijuana and LSD.

More commonly now, since the age of psychedelia ended in the early-70s, the term is used solely to describe things that seem inspired by or seem to replicate the experience of mind-altering drugs. The term is most often applied to art that utilizes bright colours and bizarre patterns or music that uses strange, non-standard timing signatures, keys, chords, and the like. The term is somewhat synonymous with trippy.
