Optical Wonders

Got this from my college brods and sis. This is amazing.

What's with this picture?
Follow these instructions:

1. Relax and concentrate on the 4 small dots in the middle of the picture for about 30-40 seconds.
2. Then take a look at a wall near you (any smooth, single colored surface).
3. You will see a circle of light developing.
4. Start blinking your eyes a couple of times and you will see a figure emerging.
5. What do you see? Moreover, who do you see?

Enjoy!
