Does something exist outside or besides the Godhead?
From my understanding of TES lore the Godhead contains the entirety of Aurbis, the past, the present and the future all within his Dream, with him constantly sleeping.
Chim is realisation that one is within the Dream, but still separate and unbounded from and by the Dream, with limitations of the world being illusory.
Zero-sum is almost an opposite of the Chim, with realisation that one is within the Dream but not separate, which somehow completely erases that person from existence.
Amaranth is transcendence of the Godhead, with one not only realising their separatedness from the Dream but even transcending the Dream and becoming a/the Godhead in their own right.
My questions are: does the person who achieves Amaranth becomes and supplants the Dremer? Does this person exist somewhere besides and beyond the Dreamer? Does this person exists within the Dream, thus creating an Inception like situation of the Dream within the Dream? And finally, does there exist a higher tier reality within which the Godhead exists, if no, where does the person that achieved Amaranth goes?
