Natural numbers can be "represented in a mind", in fact in any
mathematician's mind.

Not those which make the set ℕ empty by subtracting them
∀n ∈ ℕ_def: |ℕ \ {1, 2, 3, ..., n}| = ℵo
like the dark numbers can do
ℕ \ {1, 2, 3, ...} = { }.
 The set of natural numbers is never empty. What happens is that you decide which of its elements complies with the definition of elements of the new set, and remove the rest from consideration.
The new set defined by individual elements cannot be equal to ℕ. The set defined collectively can. This shows the difference between definable and dark numbers.
