The human eye is a master of deception, capable of creating optical illusions that deceive even the most discerning observer. One such illusion is the ability to see a face behind a wall, as if the mind's eye has conjured up an image from thin air. This phenomenon, known as pareidolia, allows us to perceive patterns and shapes where none exist, much like the way our brains can trick us into seeing a familiar figure in a crowd.
