The Nature of Matter
All matter is made up of little bugs. When they know I’m looking a certain direction, they gather themselves together to form what should be there. Everything behind me, though, has devolved into masses of crawling bugs. Only when I turn around (and they know when I will) do they form into the things behind me.
In my mind’s eye, though, I know they are crawling around behind me and that everything I see is really made of minute bugs.
