hallucinoid experience

hallucinoid experience
   An umbrella term for a variety of sensory deceptions which may accompany *hypnagogic or *hypnopompic hallucinations, but which are not themselves classified as hallucinations. An example of a hallucinoid experience is * sensed presence, i.e. the intuitive feeling (rather than perceptual impression) that someone or something is nearby. The American psychologist and philosopher William James (1842-1910) regards such phenomena as imperfectly developed hallucinations, hence the characterization 'halluci-noid'. According to the Canadian psychologist and sleep researcher James Allan Cheyne, factor-analytic studies indicate the existence of three separate clusters of hallucinoid experiences. The first cluster, referred to by Cheyne as * intruder, includes sensed presence, * visual, * auditory, and *tactile hallucinations, and feelings of anxiety. The second cluster, called * incubus after the mythological creature that sits on the chest of the tormented sleeper, comprises pressure on the chest, breathing difficulties, pain, and associations with impending death. The third cluster (designated variously by Cheyne as * illusory movement experiences, unusual bodily experiences, and * vestibular-motor hallucinations) includes a sensation of flying, falling, or floating, as well as elevator feelings, spinning sensations, *autoscopy, and * out-of-body experience.
