Obviously blind people can't "see" in the normal sense of the word. But, I was thinking, when I was stoned (like you do), what do they actually see? Is it like, when you have your eyes closed, or it's pitch black and all you can see is black? Or doesn't the brain/optical nerves even pick that up? So, do they not see at all? Their eyes are open, but there is nothing. Not even black... just... nothing. Yes, you're probably as confused as I am writing this. I have always found it impossible to imagine "nothing". So, what do they "see"?
