A gustatory hallucination is any hallucination which involves the sense of taste. A common example of this is a strong, unpleasant metallic taste in one's mouth. Another example is a strong sweet taste in one's saliva, which makes it taste like molten sugar. These types of hallucinations can cover a wide range of potential tastes and are relatively uncommon compared to other types of hallucinations. They can be either pleasant or unpleasant, depending on the users like or dislike of the given taste.
