I find it so interesting that this happens so quickly and then rather permanently. Like your brain needs some time to figure things out, but then it just flips a switch and then everything seems normal.
Just like with those people that had their vision changed (I think it was via mirror glasses or something like that) so that they would see upside-down (or was it right and left reversed?). They just adapted to it in a short while and then it was normal. And when they took off the glasses it was strange to them for a while before they adapted back to their normal vision.
