 Why do when you cover your eyes you see funny patterns and colours?

The bit of the brain responsible for analysing what you see tends to get involved with your habit circuits and to pre-judge what you are going to see. This is why Samurai can become "invisible"; they put themselves into positions where no-one expects to see a man and so they are simply "overlooked".

When you suddenly cut off the supply of images, the brain and habit circuits keep trying to give an image but without having any data to interpret so they just show you jumbled up colours until the habit circuits grasp that you're not seeing anything.

Hope this helps

Blessed be.
