The term ''illusion'' refers to a specific form of sensory distortion. Unlike a [[hallucination]], which is a distortion in the absence of a stimulus, an illusion describes a misinterpretation of a true sensation. For example, hearing voices regardless of the environment would be a hallucination, whereas hearing voices in the [[sound]] of running water (or other auditory source) would be an illusion. | The term ''illusion'' refers to a specific form of sensory distortion.
