Narration is the use of a written or spoken commentary to convey a story to an audience. Narration encompasses a set of techniques through which the creator of the story presents their story, including: Narrative point of view: the perspective (or type of personal or non-personal lens) through which a story is communicated.
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.
The hallucination may take the form of sounds, or the person may see things that don't exist, such as moving objects, or a formed image, such as a person (the person may think they've seen a ghost). Hypnagogic and hypnopompic hallucinations are particularly common in people with narcolepsy.
