Backtrack the game
Have you ever imagined that in fact, we are in a four-dimensional space, but the body perception function has not yet been developed, and we cannot perceive, just like we draw a three-dimensional map on a two-dimensional plane, when you are immersed in the illusion of a three-dimensional picture, you put your own perception in the two-dimensional world, see a higher dimension in the two-dimensional world, understand the higher dimension, but the premise is that you are in a two-dimensional world.
However, when we jump out of this three-dimensional illusion and think of this three-dimensional picture as seeing a real two-dimensional picture, our perception comes to the three-dimensional world, which is the world you and I are in now.
