Quantum erasing occurs already in arithmetic, by amnesia, i.e. classical memory erasing, which fuse the first person experiences. I agree with Zeilinger that the quantum state is just a first person (plural thanks to the tensor product) state description, but the divergence and convergence of the histories leads still to “many-histories” or “many-dreams”, which confirms the many dreams internal interpretation of elementary arithmetic implied by “simple” Mechanism. Mechanism is mainly “One-Person—Many Dreams” somehow. First person plural is a way for that person to say “hello” to itself in the coherent set of sharable dreams. Maybe some people have a too much naive conception of God and Universe, which is normal when metaphysics and theology have been taken out of science since so long (to exploit fear and wishful thinking for special interests).
