KAKOPSIA

The term kalopsia comes from the Greek wordskakos(bad, unpleasant) andopsis(seeing). It is used to denote a negative affective connotation of sensory, illusory, and hallucinatory phenomena, in the sense that these are perceived as ugly, sinister, and/or menacing. The term kakopsia is used in opposition to *kalopsia (i.e. seeing things as beautiful, friendly, and/or comforting).
