Comment on 4th dimension doesn't exist because even 1D or 2D themselves are not real.

But… You can perceive 2D things. Like this text. Or a drawing.

This text or drawing is not really 2D. Down at the atomic/molecular level they are still 3D particles. We add just abstracting it as 2D.

The text on your screen doesn’t exist as molecules. The text exists as the light travelling between your screen and your eyeballs.
The length light has to travel to reach your eyes is three dimensionak, but the actual shape of the text is still two dimensional.
Then there is the light itself, which has wave-particle duality; a light particle has no discernable border, and can be described as a one dimensional point in space, with a two-dimensional wave function.
