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.
Hypnagogic hallucinations are often auditory or have an auditory component. Like the visuals, hypnagogic sounds vary in intensity from faint impressions to loud noises, such as crashes and bangs (exploding head syndrome). People may imagine their own name called, crumpling bags, white noise, or a doorbell ringing.
