hallucination

A hallucination is a sensory experience of something that does not actually exist and has no basis in reality. Hallucinations can be caused by mental disorders or toxic substances.

A hallucination often takes the form of visual images or noises, as in Sangeet saw a hallucination of sparkling lights.

Hallucination can also be used to refer to the sensation caused by one of these false sensory experiences, as in Roman was suffering from drug-induced hallucinations.

More generally, hallucination can be used to mean a false notion or belief, as in His idea of what life was like in Canada was nothing more than a silly hallucination.

Hallucination is similar to the words illusion and delusion, which also describe false beliefs or experiences. An illusion is a false image that is a result of a distortion or manipulation of actual things. For example, makeup can create the illusion that a person is younger than they actually are.

A delusion is a persistent, false belief that may or may not be partially based on reality, as in The athlete’s huge ego constantly made him have delusions of being unbeatable.

Example: The explorer suffered from terrifying hallucinations of ghosts and phantoms after eating the toxic mushrooms.

The first records of the term hallucination come from around 1640. It ultimately comes from the Latin (h)allūcinātiō, meaning “a wandering of the mind.” Hallucinations are produced entirely by a person’s mind and are not based on anything actually happening outside of it.

Hallucinations are often caused by toxic substances, such as mushrooms, or mental disorders such as schizophrenia. Some of the most common types of hallucinations include feeling like something is crawling on your skin, hearing sounds or voices, or seeing lights or patterns.
