I used to believe that during the night while we slept, we were on the part of the world that was "upside down." Of course our nighttime was China's daytime, so that's when they were upright. Sometimes I would get a floating sensation as I drifted off to sleep, and I assumed that I was feeling the world rotating into an upside down state for me.
