A member asked:
What is the difference between illusion and delusion?
A doctor has provided 1 answer
Perception or belief: An illusion is a primarily perceptual disturbance where something looks like something else. A delusion is a fixed false belief that is not a function of misinterpretation but rather a form of preformed and self referential belief that is deeply entrenched and not connected directly to directly observable data in the outside world.
