I think what she's asking is if these beings are collecting the spirits of the dead, why are people reporting seeing ghosts.
they take their souls. i think the spirit must be something different. or it could be that ghosts are spiritless/soulless and that's why they wander around.
they don't exist, just like the grim reaper doesn't exist.
