As I was thinking about your post, WePow, I came across this:

http://www.visualperceptual.com/

I was fascinated with the possibilities (read the first few paragraphs). It would appear that the cognitive/thoughts/trigger causes a visual change whereas this site claims it's visual difficulties that cause cognitive problems; I wonder if T switches positions in some sort of way that your "mind" switched positions in the past or if your mind went further before and T moving is "good"/means you are more "steady" (kind of like you sit in one place/position and can move your eyes, see different views; maybe your perception is doing that, taking the place of your eyes while your self is "sitting" in one place/position).
