What is an illusion?

An illusion is a deceptive perception or appearance of something that is not consistent with the actual reality. It is a distortion of the senses, causing a person to perceive something that is not true or accurate. Illusions can occur through various sensory modalities, such as visual, auditory, tactile, or cognitive. They can be created intentionally as a form of entertainment or can occur naturally due to the limitations or misinterpretation of the human brain and senses. Illusions often challenge our perception and highlight the subjective nature of reality.
