Illusions, delusions, and hallucinations are often considered to mean the same thing, even though the three terms have different meanings, you know. However, what is certain, all three are commonly experienced by people with certain mental disorders, such as schizophrenia or psychotic disorders

Illusions, delusions, and hallucinations are terms that are closely related to mental he alth. Mental patients who experience this condition find it difficult to distinguish what is real and what is not.

Difference between Illusions, Delusions and Hallucinations

To be clearer and not misguided again, consider the following explanation regarding the difference between illusions, delusions, and hallucinations:


Illusion is a condition when the stimulus obtained from one or more of the five senses is misinterpreted, so that it does not match the actual reality. This condition can sometimes be experienced by he althy people, but is more common in people with schizophrenia.

What are some examples of illusions? People who experience visual illusions can feel like they see certain animals passing in front of them, when in fact only people passing by on bicycles or riding motorbikes. Sometimes people who experience illusions can also see objects that are larger or smaller than their actual size.

In auditory illusions, people who experience it can feel like they hear the sound of someone running, but actually the person is just walking.Another example could be hearing someone crying, even though the sound is coming from the wind or someone talking.


Delusion is one of the typical symptoms of mental disorders, such as psychosis, schizophrenia, personality disorders, bipolar disorder, and dementia. However, sometimes delusions can also be experienced by people who are depressed or have Parkinson's disease.

Delusion is a condition in which the sufferer cannot distinguish between what is real and what is not. People who suffer from delusional disorder will often assume what they are experiencing, seeing, or hearing is really happening and convincing others that it is fact.

There are several kinds of delusions, which are often also called delusions, namely paranoid delusions, grandiose delusions, erotomania, and bizzare delusions. An example of a paranoid delusion is when a person feels that someone else hates or wants to hurt them, when there isn't.

While examples for bizzare delusions can be various and odd. When experiencing this delusion, a person will believe something that tends to make no sense, for example, their soul and mind are controlled by television or they are about to be kidnapped by extraterrestrial beings.


Hallucinations are perceptual disturbances that make a person hear, see, smell, and feel something that is not really there. Unlike illusions which are errors in sensory perception, the sensations in hallucinations are created by the patient's own mind without any real source.

An example of a hallucination is when the sufferer sees an object or hears something, but in fact it is not there and is not seen by others. An example of this condition is that a person feels that he or she hears whispers or the voice of another person talking to him or her, even though he or she is alone in the room.

Hallucinations are usually caused by certain psychiatric disorders, such as schizophrenia, dementia, borderline personality disorder, and bipolar disorder or depression with psychotic symptoms.In addition, people with neurological and brain disorders, such as Parkinson's disease, delirium, stroke, and Alzheimer's disease, may also experience hallucinations.

Well, now you know the difference between illusion, delusion and hallucination, right? So, don't get me wrong again in using these three terms, okay.

If a person experiences illusions but is not accompanied by other complaints, generally this condition is nothing to worry about, especially if it only occurs occasionally. However, if delusions or hallucinations appear, you should immediately consult a doctor.

Recurrent illusions, delusions, or hallucinations should be consulted with a psychologist or psychiatrist. That way, doctors can diagnose mental disorders or diseases that cause them, and provide appropriate treatment, such as psychotherapy or drugs.
