Top 10 Types of Illusions and Hallucinations


When we hear the words “hallucination” and “illusion,” we think of some crazy person looking around and seeing stuff that isn’t there. You don’t have to be crazy to experience them. Illusions and hallucinations are types of distortions in reality.

Here are the top 10 types of illusions and hallucinations.

 Environmental Tilt:

There are people who experience environmental tilt, Their world is turned upside down, or at least that’s their visual perception of the world. It is usually a tilt of 90 degrees or 180 degrees. In some rare cases, it can be even more unusual rotation such as 30 or 150 degrees.

Charles Bonnet Syndrome:

In 2016 a woman developed an unusual problem with her vision; she hallucinated visits by pigeons in early evening hours. She did not have any mental issues and was entirely sane but had vision loss. Her hallucinations were known as Charles Bonnet Syndrome. In vision loss, our eyes receive less input from the world outside, and it sends fewer data to the brain, but we know that our brain is hungry for actions, so it makes up things that aren’t there. In other words, your brain shows you stuff that isn’t there to fill your blind spots.


All the colors are made in our brain, and the colors outside are of different wavelengths of light bouncing off objects. There’s a type of hallucination known as chromatopsia. In this, a person sees more color than there actually is. It’s like turning up the saturation and color of your computer monitor, except in real life.

Macropsia And Micropsia:

When you see something, you can determine its size, it looks easy, but it involves a lot of processing in your brain. Macropsia and Micropsia are two illusions that perceive things as too big or too small. It means that a person might see the size of an ant something to an 8 feet horse and an elephant of a few centimeters.

 Exploding Head Syndrome:

Fifth in the list of top 10 types of illusions and hallucinations comes exploding head syndrome. Sleep is supposed to be peaceful but not for people with exploding head syndrome. They experience disruptions while falling asleep or waking up in the form of hallucinations. To be more specific, such people experience loud explosion noises in their heads that shocks them awake. These explosions are accompanied by fear and are not painful. Explosions could be similar to light cracks, fireworks, gunshots, beeps or as heavy as an atomic blast.

 Gustatory Hallucinations:

Gustatory Hallucinations are going to leave you with an awful taste in your mouth. Some people can imagine tastes when they want to, but most of the time they are unpleasant tastes like rotten apples, stale cigarettes, or other unpleasant tastes without even eating something.

Olfactisms And Odor-Color Synesthesia:

There are a group of people who experience strange and mixed up perception of the world due to a condition called synesthesia. These experiences are linked with words, tastes, or letters and colors. For example, you listen to the word John, and you suddenly smell rotten eggs.

 Hallucinatory Halitosis:

Sometimes a person may perceive that they are having bad breath, while in reality, the smell is all in their head. It is known as Hallucinatory Halitosis. They mostly experience bad smells that are not present.

 Ictal And Postictal Religious Experiences:

Some people experience religious hallucinations due to epileptic seizures. A seizure of such kind can make a person’s faith stronger in religion, but at the same time, it can make him convert to something else.

 Supernumerary Phantom Body Parts:

Some folks believe that they have some supernumerary extra body parts. Commonly they believe they have another pair of hands or feet or can be eyes too.

These all top 10 types of illusions and hallucinations are games of brain!
