I'm sure it ISN'T the same. Nor would I want it to be. That is what makes the world so interesting and diverse, though not always for the best.
How do you know that your experience of consciousness is the same as other people’s experience of consciousness?
Depends upon your "Wiring" . . . Those clusters of Synapses that fire in my head are quite different then someone else's . . . It took 50 years with a Genetic start (Shared from my Parents), and the right amount of Environmental Influences and Life's Experiences to get them to HOW they are right now . . .
So unless, I share all three of those things EXACTLY with someone else, My consciousness is different.
