Today I had a vivid memory of being like 8 and sitting upside-down in a spinny chair, like with my feet in the air and looking toward the ceiling, and spinning as fast as I possibly could until I was so dizzy and disoriented that my mind was convinced that the ceiling was the floor and I would feel like I was floating over this ceiling/floor.
