Also referred to as hallucination normale or 'normal hallucination'. The French term hallucination psychonome is indebted to the Greek words psuchè (life breath, spirit, soul, mind), and nomos (law). It translates loosely as 'hallucination in accordance with the mind's laws'. It was introduced in or shortly before 1930 by the French psychiatrist Pierre Quercy to denote a hallucination that can be evoked in any individual susceptible to suggestion. As Quercy's compatriot Henri Ey (1900-1977) notes, the notion of hallucination psychonome would not seem to have a bearing on hallucinations proper, but rather on *illusions (more specifically, on 'normal illusion-ary phenomena').
