Again interpretation, if death isn't literal, there is no use using it.
I have no idea what you are trying to say. Nomura has said that 'leaving the world', i.e. essentially dying (and remember that in Japanese the words for world, realm and World as they are translated in KH are all the same word) is known as 'sleep' in Kingdom Hearts universe.
So any imagery revolving around sleep, being born, reborn etc is obviously connected to the cycle of life, which involves moving between realms.
And yes, it is a fact that the cycle of life involves moving between realms in KH.
All hearts are born from KH, ASoD says so in KH1. KH is inside the RoD. That means every heart must pass from KH through the RoD and into the RoL to be born. And if 'death' is simply 'sleep' in the KH universe, then it makes sense that when they die (as in, their soul-battery runs out and they shuffle off the moral coil), they would go back there to sleep. That's what the Org was taking advantage of with their fake KH, after all; intercepting the hearts and forcing them to gather in their own KH instead. Because in KH, nothing simply disappears. Things you think disappear from (leave the world, essentially die in) your realm simply go to another. The darkness in someone's heart eats them alive and they disappear from the RoL. But the heart appears in the RoD, and the body appears in the RoI.
That's why it makes sense for Riku, trapped in the RoD without a body, had to have been 'reborn' to move to the RoI (where CO was).
