Difference between hallucinations and delusion

Answer 1

Delusions and hallucinations both distort reality. Hallucinations mainly revolve around your 5 senses (hearing, seeing, smelling, tasting, & feeling something that isn't there). Examples of hallucinations would be hearing voices when others can't hear the same voices and the feeling of spiders crawling on your body when in reality there are no spiders. Delusions, on the other hand, are false beliefs or ideas, believing in something that's not true. Examples of delusions are the belief that someone is out to spy on or harm you

Answer 2

A hallucination is typically something someone sees/hears/smells (uses the 5 senses) that is not actually there (example: seeing a person in front of them but that person isn't actually there).

A delusion is more so a belief (example: believing I am the president of the U.S. or that the government installs cameras in birds).
