I was talking about the virtual universe.
It is a virtual universe. We can't prove it exists beyond what we conceptualize. We can balance numbers and speak of it as a shared concept - but we could really all be dreaming.

Or I could be dreaming everything, including moments shared and responses I give.

How do I know you (or even I) for that matter - really exist.

>Simple question: in your opinion, is our mind a physical phenomenon that cannot be accounted for by the fundamental forces and particles?

I have read accounts of spiritualism - American Indians - I think - felt that life was a dream - and death was the awakening.

Row row row your boat
Gently down the stream
Merrily, merrily, merrily, merrily,
Life is but a dream.

If we could only shed the nightmares!
