When you smell something that really isn't there.

I've had many olfactory "hallucinations" like when I smell mustard & there's none around!

Hallucinogen 

A type of drug that produces Hallucinations, whether they be auditorial or visual. A Hallucination is something that inst real but you are aware of it by seeing/hearing it, so Hallucinogens create sites and sounds that arent real.

My second time taking LSD, a Hallucinogen, i store at my ceiling and hallicunated beautiful girls faces swirling around in geometric patterns, changing colors.
