Is this how the universe works?

Imagine there are a set of fundamental traits that a particle (or imagine it as a person if you like) can have.
Now imagine a universe with multiple dimensions some of which are very fine and it is easy to pass from one point to another (e.g. space) some of which are not fine and it is as difficult to pass from one category to another (e.g. positive and negative charge).

Now a particle with exactly the same traits as another particle is the same particle as the other particle not just in terms of being identical - they are genuinely the same thing because there is no other way in which they can be different - they occupy the same space in the multi dimensional universe. Meanwhile something with very similar traits is in a sense "overlapping" and thus next to the other particle and able to influence it.

Make sense?

These dimensions require limits to how they can be traversed to be visible to us. Time is protected by entropy and space is protected by the speed of light. Maybe others are protected by other factors like that OR maybe the lack of these things defines why they are not as obvious.

'protected by' is rather a vague phrase here. What exactly is 'Time is protected by entropy and space is protected by the speed of light' meant to say?

That said, entropy doesn't protect time; it only prevents time from going backward, sure, according to Hawking. And the speed of light protects space? I have never heard of that.

Perhaps you could clarify the matters? ;)

What I mean is that if one could traverse time or space in any direction at an unlimited "speed" then it would cease to be particularly clear distinction.
If there was no speed of time limitation and entropy then it would start to be difficult to tell whether two pieces of space were close or far away so it would loose its structure.
Make sense?
ideally i'd like to see those things as things that in sense naturally emerge from the dimensions themselves and how they relate.

What you describe sounds suspiciosly like bosons in particle physics. Bosons with identical "traits" or quantum numbers can all fall into the same state and do cool stuff, like Bose-Einstein condensation of atoms. The other class of particles, fermions, can't do this and your "difficulty" idea is then analogous to the Pauli exclusion principle.

Also your "influence" sounds like quantum entanglement, exemplified by the EPR paradox. But even then the apparent non-local behaviour that you ponder has recently been shown to be local after all, even if decoherence doesn't get you first.

Interesting, you managed to posit a whole load of quantum mechanical phenomena in three paragraphs!
