   Also known as a scenic hallucination and holocampine hallucination. All three terms are used to denote a *compound hallucination in which the entire sensory input is replaced by hallucinatory percepts, thus giving rise to a totally different perceptual reality. The British physician Henry Maudsley (1835-1918) captured this phenomenon aptly when he wrote, "In the delirium of insanity it is not an uncommon thing for the sufferer to see and hear persons who are the mere phantom-creations of his disordered brain; and when the delirium is of an acute character these are so vivid and active, and have such full possession of his senses, usurp his attention so entirely, that real persons and voices can make no impression upon him. He is cut off from the actual world by the very intensity of their turbulent activity, which inhibits or blocks the true functions of the senses, so dislocating the connections of them that they seeing see not, hearing hear not, touching feel not; like a person in a nightmare, he lives in a tumultuous ideal world." * Deathbed visions taking on the quality of a panoramic hallucination are sometimes referred to as * total hallucinations.
