    Does anyone know why we experience optical illusions?

    Because the brain does its best to figure out what's in an image. Illusions are images that purposefully have two valid, yet distinct interpretations (like the famous one with either the faces or the vase). Most people won't even notice the alternative interpretation until someone tells them it's there.
