Consciousness, by definition, is an emergent property of complex electro-chemical processes in living, organic tissue. [emphasis mine]

Well, if you choose to define it that way…fair enough, I’ll bite.
But I think we’ll run into trouble debating “complex electro-chemical processes” because: (1) Neuroscience is still working out how those processes actually work, and (2) the brain is NOT entirely electro-chemical, in my opinion.
You see, it’s my belief…oops I mean hypothesis…that consciousness, memories, and other high-end thinking skills are based not on biochemistry, but on the actual electricity created by the brain. Specifically, the electrical patterns created by the organization of neurons in the brain. These patterns are very simple and limited in number (kind of like how the English language has 26 letters to describe 70,000 common words and millions of potential “nonsense” words; or how you can use an Erector Set to build countless, varied & unique objects with just a small set of specific parts) but – here’s the rub – they probably vary from individual to individual.
(BTW, I came up with this theory 20 years ago. Since neuroscience isn’t my field of expertise, I never wrote a thesis or suggested experiments to test this theory. But as I watch the field of neuroscience evolve, it’s interesting to see how they’re starting to figure it out. Except, of course, the stubborn assertion that the brain is 100% chemical.)
Oh, there’s no question that human/animal consciousness requires a biochemical system to exist. At least, while we’re alive.
Ghosts have no matter. We can assume that is fact. Therefore, ghosts must have energy. What kind of energy? How do you measure it? How is that energy connected to living human consciousness? Based on our current level of science, these are questions we can’t answer with any level of certainty yet.

If you contend that the picture you linked is proof of a ghost looking at the car he just died in,

I agree, that photo does not prove that the ghost was the driver.
He could be the ghost who caused the crash in the first place.
