An illusion has an external stimulus that causes an erroneous translation. Anyone, even a person with intact sensorium, can have an illusion. An example of an illusion is "seeing" water on the highway, which is really only heat waves. A hallucination has no external stimulus. An example of a hallucination is the alcoholic seeing spiders crawling on the ceil-ing.
