These illusory experiences include such stock examples as dreams, hallucinations, mirror images, the after-images of the sun, the bent appearance of a straight stick that is immersed in water, and the apparent motion of trees experienced by those traveling down a river. He also mentions such cases as the double image of a candle that appears when one’s eyes are distorted, the shimmering, changing appearance of colors on a dove’s neck, and most interestingly, the fiery circle that appears when a burning stick is whirled rapidly through the air.
