This is rad, love discussing ontology, and I've always believed there is simple consciousness.

I would also add that there could be more "complex" states consciousness; of compositional universes.

Zoroastrianism, one of the very first cultural sects, believed in these concepts and used different substances and meditative states to access these plains of existence, suggesting that energy never dies but is simply moved from plain to plain. Accessing your own consciousness is said to be the key to travelling above and below.

Awesome post., Thanks for the read.
