Do you have hallucinations in your blind spot?

Oliver Sacks studies the visual regions of the brain and hallucinations.  In this talk he describes people with sugnifficant vision loss seeing everything from geometric shapes to people and cartoons.  It is a very interesting talk.



I do see patterns in my blind spot.  Its not anything I can describe.  Its just chaos or fractals.  I'm not user if this is normal or if I have what he describes.
