Where else?

Even if that is true the brain is still in the impossibility to create sharp and clear description of an event or experience.
It would be like a drunkard description so no only an alive consciousness can provide a sharp and clear description.

And you know this how? This is just another unsupported assertion. What's your evidence that this would be the case?

You're imagining consciousness is like a linear phenomena that if you turn down the brain, you turn down the consciousness. That's an absurd assumption.
