Illusion Definition
An illusion is a condition in which one or more human sensations cannot perform their function correctly, and one of the senses is deceived by the other. The important thing is; that there must be some external stimulus in the state of the delusional sense and that sense misperceives it or is deceived. An example of an illusion is to see a mirage in the desert, in which there is an external stimulus, i.e., waves of light, but the sense of sight deceives them and presents the sand as water. Usually, the most involved in this condition is the sense of vision, and this type of deception is also called Optical illusion / Visual illusion.
Types of Illusion
Optical illusion:- Optical illusion is a deception in which a person sees and imagines something contrary to reality.
Auditory illusion:- Auditory illusions are incorrect perceptions of an actual sound or external stimulus.
Tactile illusion:- A tactile illusion affects the sense of touch.
Temporal illusion:- A temporal illusion is a falsification in the perception of time, which happens when the time interim between two or more events is very narrow (usually less than a second). In such circumstances, a person may momentarily observe time as stopping, slowing down, speeding up, or running behind.
Hallucination Definition
Hallucination is the name given to a condition in which one or all human senses make mistakes or errors and cannot perform their function correctly. Without any external stimulus, the sensation of this stimulus (such as sound or smell, etc.) is manifested in the brain, such as seeing the non-existent, hearing the sound without anyone speaking, smelling the smell even though there is no smell, Etc. This is due to various types of defects in the brain and nerves. It is recognized in psychiatry as a severe mental condition or disease.
Difference Between Illusion And Hallucination
The state of illusion is different from hallucination. In hallucination, no sense can play its role correctly, like an illusion, but in a state of hallucination, there is no external stimulus for the movement of the senses. And without any external stimulus, the sensation of that stimulus (such as sound or smell, etc.) is evoked in the brain. Hallucination is generally recognized as a psychotic condition or disease in psychology.
