What do you see when you have a optical illusion?

When observing an optical illusion, the brain perceives an image that may differ from reality, often leading to a surprising or puzzling interpretation. This occurs due to the way our visual system processes information, creating effects like depth, movement, or shape distortions. As a result, we might see two or more interpretations within the same image, highlighting the complexities of perception. Ultimately, optical illusions challenge our understanding of how we perceive visual stimuli.
