>that 2D is Hell and 4D is Heaven?
This refers strictly to "the three realms" of planet Earth, which are described in Asian mythology and by Plato in The Republic, where heaven and hell are temporary states, places to incarnate into between lives on Earth. They are described as at most 900 years long, while those who sinned too much will be thrown out of the bottom of hell.

This has nothing to do with infernal or heavenly dimensions of deities or demon lords such as Baal ze Bub or Adremmelech. Although demon lords tend to have places that inhabit the same kind of beings who would be able to live in the 2D of the three realms, these are permanent residents and not humans passing by as part of samsara.
