Zombie Loophole
If you posit that souls, ghosts and zombies exist; then one who died with unfinished business, but whose death happened to turn their soulless corpse into a ravening zombie and set their ghost free; then that ghost, upon re-possessing that corpse, would find no resistance at all. Haunting your own zombie just brings you back to life.
Probably immortal, possibly with a skin condition.
I will not be taking any questions.
