I don't think I've shared my thoughts on here, but this sounds a lot like my thought process: what if you start with nothing but consciousness, then find a path to a physical universe?
Consciousness is inherently about awareness, so at some point the consciousness would be aware of itself. Now it has the concepts of before/after, and from that opposites, incrementing, subtracting, 1 dimensional space etc. Eventually through this process you could "spawn up" other consciousnesses each expanding their individual bubbles of experience and understanding, eventually getting complex enough to create an entire universe with physical matter that can be experienced by other consciousnesses.
There are a lot of similar ideas in various ancient/traditional spiritual/esoteric teachings. "Consciousness first" is actually the more typical assumption among the traditions that have something we'd label as a philosophy.
The problem with this line of thought is that consciousness can be damaged when it's physical container is damaged. A piece of falling masonry can be enough to shear off large parts or all of it. If consciousness was fundamentally distinct, this wouldn't be the case, would it?
