Dimension 0 is a point and a singularity.

1 dimension is a line and countless points.

Two-dimensional is a face with countless lines.

3d is an object with countless faces.

4-D is an infinite number of bodies and an infinite number of parallel worlds (an infinite number of your own bodies). Time is just the process of your "consciousness" choosing the direction of the universe and things. We feel that there is only one universe, but in fact, your consciousness has experienced infinite parallel universes every millisecond, and there is no past, present and future, all of which exist in N-dimensional space at the same time.

Dimensions 5, 6, 7, 8, 9 are too difficult to understand and express.

Our world is actually similar to the scene described in The Matrix, but it is much more complicated. The only thing we really have is "consciousness"
