Which is separate from yours yet perceived by both of us....
talk your way around that one.
The whole separation argument is false. And that's not just my opinion it a logical fact of existance and a reality that is not merely ostensible, as opposed to a reality that has yet to be defined on this forum by its proponents. Until you can present a concise definition of the word "reality", any statement to the contrary of its commonly given definition is false.
