Illusions are simple: perceptual distortions, seeing things that aren't there because of low lighting, atmospheric distortion, etc. Once light is shined on the cause, the illusion disappears. Delusions are fixed patterns of thought that do not respond to reality. Hallucinations are psychotic manifestations that have little to do with reality. The latter two are usually brought on by drugs or mental illness.

Stimulus: Hallucination is a false perception while an illusion is a misperceptions of a real stimulus--hearing voices with no stimulus is a hallucination misinterpreting the sound of the radiator as voices is an illusion.
