Yeah, but the map is not the territory.
I am not convinced they are different in the case of things that "we
can't perceive ... from the physical world."
All this to be able to cleverly claim « Santa Claus really exists » with a

There's a practical reason why people make a difference between a rock, a
brain thinking about a rock, a brain thinking about a brain thinking about
a rock, and a brain thinking about the set of all possible brains thinking
in all different manners about all different kinds of rocks... even though
each of those cases must be embodied by some part of the physical world...
and even though all of those cases are referring to rocks.
