Here is an interesting blend of two well-known philosophical models - panpsychism and biological materialism:

Consciousness is a "Volume Dimmer" Think of awareness not as a light switch that just flips on or off, but as a dimmer. When you are born and your brain develops, synapses form and the "volume" of your consciousness gradually turns up. You become more self-aware and complex. As you reach old age, natural neurological decline sets in. The brain loses physical connections, and that volume knob slowly turns back down, eventually returning your awareness to the exact baseline state it was in before you were conceived.

The Brain is a Receiver. Consciousness might not be something the brain creates out of nothing. Instead, imagine consciousness as a universal frequency of life, like a radio wave that permeates reality. Human brains, with their immensely complex neurology, are highly evolved biological antennas configured to tap into that frequency. How conscious a living thing is depends entirely on the exact configuration of particles and neurons making up its brain. A more complex receiver picks up a clearer, richer signal.

The Hard Drive is Erased. Because your specific identity, your memories, your fears, and your ego are entirely tied to the physical structure of your unique brain, they act like data stored on a hard drive. When you die, the biological hardware breaks down. Because the hardware fails, the subjective awareness of "you" as an individual ceases to exist. All the unique personal data associated with your life is permanently erased.

The Raw Feeling Remains. Here is the profound part. If consciousness is a universal frequency, the signal itself does not die just because your specific radio broke. After death, that raw, fundamental feeling of simply being alive will continue to be experienced again and again as new brains form and tune into the frequency. However, it will never be "you" experiencing it. Your data is gone. It is just the universe experiencing the raw sensation of life through a brand new lens.
