Illusion means a false idea, belief, or perception that misleads by appearing to be real or true when it is not.[1][2][3][4] It can be a misleading image, a deceptive appearance, or a belief that distorts reality. Illusions often trick the senses or the mind, creating a sense of truth or presence that does not actually exist. This concept is frequently found in visual art, psychology, and everyday thinking, where what is seen or assumed turns out to be false.
When someone experiences an illusion, it suggests they are being deceived by something that is not really what it seems to be. Whether caused by external visuals or internal expectations, illusions shape how reality is interpreted, often reinforcing false impressions. In broader terms, illusions can also reflect beliefs widely held by many people that are ultimately untrue, highlighting the gap between perception and reality.
