Freud argues that illusions are appealing because they allow us to experience pleasure rather than pain, but they can be disrupted by encounters with reality. While optical illusions in images may trick our eyes into perceiving motion or differences in shape and size that are not real, turning our head can reveal hidden meanings and messages in the patterns.

1. Illusions commend themselves to us because they save us pain and allow us to enjoy pleasure instead. We must therefore accept it without complaint when they sometimes collide with a bit of reality against which they are dashed to pieces. --Sigmund Freud (Austrian neurologist and Founder of psychoanalysis) [1856-1939]

9. If you take a look at the following picture , let me tell you ... it is not animated. Your eyes are making it move. To test this, stare at one spot for a couple seconds and everything will stop moving. Or look at the black center of each circle and it will stop moving. But move your eyes to the next black center and the previous will move after you take your eyes away from it.... Weird

11. Are the purple lines straight or bent?

12. Which circle in the middle is bigger?

13. Do you see gray areas in between the squares? Now where did they come from?

14. You should see a man's face and also a word... Hint: Try tilting your head to the right, the world begins with 'L'

15. Is this possible!?!
