What is a sub dimension?

Allow me to introduce a new idea.

In this video I have posted pictures, which visually explain my idea, about a sub-dimension between the fractal and third dimension.

Observe:
I know it already exist an idea about a dimension between the fourth and third, called fractal, but I think this fractal dimension instead exist between sub & fourth dimension, more like:
a sub-dimension exist between the third & fractal dimension.

However.

But what do I mean by Sub-Dimension?

Well, to understand that, you have to think one dimension backwards. And that what we see around us, and the terrain (not including solids) we stand on, is two dimensional and not three. But back to the question! If you imagine the terrain in the 2d creature's world (megaman NES), it is not two dimensional, but one. There is also a sub-dimension (flatlander short story) between the second and third dimensions, where the terrain, however, is two dimensional, not one!

This means that the terrain is spread over the entire 2D room (volume terrain), and that a creature there can turn around in all directions and see trees, bushes, flowers, grass and lakes and more. To be able to see something and so that not everything overlaps, they can focus their vision in front of, behind and inside objects with x ray vision! They can also move freely through the solid terrain!!!

Then imagine this as a three-dimensional terrain, that is, a sub-dimension between the third and fourth dimensions.
How cool would it have been, to see all that?

Perhaps this is the explanation why spirits and ghosts pass through walls and solid objects.

Thanks for watching this to your all!
Take care of yourself!
