illusion,

n a mistaken or erroneous perception of an object external to the individual. In some cases, the laws of physics explain the errors. In others, the explanation lies with the perceiver. Illusions should be distinguished from
hallucinations, which are perceptions that lack external stimuli, and
delusions, which are false beliefs. Illusions are seen in certain reactions to general anesthesia or intoxication.
