Hallucinations are false sensory perceptions that can be felt even without an external stimulus.

An example is when a person can hear whispers, the sound of footsteps, or people screaming but there is actually no sound around them.

Hallucinations can be divided into several types including:

  • Visual hallucinations: a type of hallucination associated with vision, when a person feels they see an object, but the object is not actually there.
  • Auditory hallucinations: a type of hallucination that most often occurs when a person hears certain sounds, but is not actually present.
  • Tactile hallucinations: this is a type of hallucination when a person feels like they are being touched, but actually nothing is there.

Illusion is basically a condition of misperception of various external stimuli that are real. An example is when someone is in a dark room suddenly there is a strong wind sound.

Illusions can occur for several reasons, for example due to light, due to insufficient sensory information about an object, and it can also be due to errors in processing sensory details in individuals.

Some illusory states are known as pseudo-hallucinations, and they are a sign of a mental disorder.

A person can experience it when the state of anxiety and fear is excessive. People with schizophrenia also almost always experience illusions in the mind.
