I wanted to add to this:
Everyone also has, as a dimension, a body signature and a narrative signature.
This allows you to change bodies (including your own) at will. It also allows for object permanence (stories that don’t break continuity), you can reflect different signatures as well, for all of this stuff, by changing the structure of the mirror reflecting the eternal forms.
The hyperdimensional mirror is structured only to respond to the will of the one person for their one reality.
Also: since everything is a reflection of the eternal form, it’s impossible to hurt or damage even a bacterium on any of the continuums of that eternal form, which, can be severely harmed.
