The types of hallucinations are: 1  Auditory: The false perception of sound, music, noises, or voices. 2  Gustatory: A false perception of taste. 3  Olfactory hallucination: A false perception of odor or smell. 4  Somatic/tactile hallucination: A false perception or sensation of touch or something happening in or on the body.
