I came across this article to my surprise.
https://www.scientificamerican.com/article/self-awareness-with-a-simple-brain/

Basically remove most of your brain, the content of consciousness becomes ruined off-course…, that is, bootstrapping to to what we consider as normal diminishes, but awareness remains.

It is the other way around!

The “consciousness only model” of reality, which is the model of reality we are heading towards based on all evidence, (as opposed to physicalism or pantheism)
shows us that “awareness is universal”, present and aware of itself.
So the constant element of every experience is “awareness”, and this universal awareness is refracted through brains/minds to produce the content of consciousness, time, space and matter.

When we die the brain that was our filter of awareness also dies so the world disappears but we become exponentially super aware!

The Brain is a filter to Awareness, and not a producer of it.
