When I was a kid, in those long moments when my mom would not! get off! the phone! to shower me with attention and answer whatever trivial and random question I had, I would lounge around and do the strange things kids do when they are bored. I developed a game in which I would lean my head upside down off the sofa or staircase and imagine an upside-down world where the ceiling was the floor and the floor was the ceiling. I visualized myself walking upon the sloping "floor" and passing by the chandeliers, floating upon their chains like strange metal trees.
