Bill, a dream is testable within the dream. The Afterlife is testable within the Afterlife. Neither one of them is testable here in the physical because they are NOT here in the physical. ;-)

And the physical is not testable in a dream or in the Afterlife...but it IS testable here.

Your assertions are based simply upon your predilection to insist that one theatre of operations, the physical, is the only real theatre that exists. You're like a chess player who will not accept the existence of checkers, whist, scrabble, poker, or backgammon...except as (in your view) insubstantial mental notions with no foundation in reality.

Every game, as I said before, is played strictly on its own board (or within its own rules and conditions) and is not testable outside of those. Observable to some extent, perhaps...able to be commented upon and debated about...but not testable.
