The more conventional perspective on QM is of a single nondeterministic world or of a single world in which events have subquantum causes. From this perspective “quantum torment”—lingering indefinitely in a near-death state—is logically possible but inconceivably improbable, something that wouldn’t happen even if you reran the history of the cosmos a googol times, because it involves the quantum dice (whether deterministic or nondeterministic) repeatedly coming up just the right way to prevent your body from finally giving up the ghost.
It’s much easier to neglect low probability events in a single universe (I should say a finite single universe) where they generally don’t occur. If low measure worlds occur, they may well seem fully real to the observers inside them.
