Try closing your eyes and navigating your home with a cane at the same time and see if it persists? Try checking if it persists when you're playing video-games? Does your sense of self go into the character? What about if you watch another person really closely?
I have a shifting spatial attention that changes according to the task at hand. The only sense in which "self" is located in my "head" is that to me the world "self" partially means things like "face" and "brain" to me and so recalling the word "self" directs my spatial attention there, in the same way that "door' directs spatial attention to the door.
But as I go through the day I don't think there is anything mentally privileged about the space right behind my eyes unless I specifically start thinking about "self" and what it means. I suspect spatial attention and the nature of how verbal concepts direct it is most of what is going on here.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
