In this illusion, you will know how our mind process the missing information and conclude the results. Can you find white arrows in the picture? We are sure you can. But are they really there? Concentrate on the black portion now. That is the actual figure that has been drawn here. However, the blank space is giving you and illusion that the white arrows are there even though they are not present. Probably if the missing pattern was not creating a familiar shape, you would not have felt the same effect.
