The term psychedelic is composed of the Greek words ψυχή (psuchē, soul) and δηλοῦν (dēloun, to reveal) and when translated means 'mind-revealing'. Characteristics of a psychedelic experience are that one's mind perceives in a previously unknown way, or outside its usual limitations, and is uninhibited. A psychedelic state can be a variety of experiences that can be induced in different ways, for example through sensory stimulation, sensory deprivation, or hallucinogenic substances. Such experiences include hallucinations, changes in perception, synesthesia, altered states of consciousness, mystical states, and sometimes psychosis-like states.
