Okay a simple (weird) logic about this
Fiction by it word is mean imagination. If you consider 4D as a imagination in your existence then you whould be 5D, imagination is just limited in your plane of existence. A question can you imagine what 5D look like???
Why we give them a 1A tiering when even they cannot imagine or make a fiction about dimension that higher then them
In fact we still 3D even when the fiction or anime or manga or the 2D thing write about the infinite dimensional in it. Are we now a outerverse level that outside a infinite dimensional???
More complex answer
Like i say above, we give R>F a higher dimension because it make what lower than that is a infinitesimall thing, that literally mean infinitely small or infinitely lack of
quantity, the lower one is infinitely lack of mass, time, distance/space, etc.. or in other word infinitely lack of every physical properties for them to exist
In other hand, if the lower one is infinitesimall it mean the higher is infinitely larger of bigger, is mean we talking about the higher infinity. And yeah set of real number is first higher infinity that also equal to the addition of a axis of dimension, so higher infinity=add 1 more dimensional axis, higher infinity of 4D is 5D and 5D is 6D and.....
