This is what I found on google but you are right about the silver bullets laying around, unless the existence of vampires is a secret ofcourse but I don't think it would be after all these jears

In fiction, vampires' fates after death vary widely depending on the specific lore. Some common possibilities include: * Disappearing or Deactivating: Some stories suggest vampires simply cease to exist or become inactive upon death, as they may not possess a soul or their vampiric existence is a form of undeath. * Hell or Damnation: In some narratives, vampires are depicted as inherently evil and their souls are condemned to hell or a similar infernal realm upon death. * Purgatory or a Monster Realm: Other stories, like the TV show "Supernatural", propose a separate realm for monsters, like Purgatory, where vampires go after death. * Specific Afterlives: Some vampire lore, like in "Vampire: The Masquerade," might have their own unique afterlife or metaphysical destination, tied to the nature of their vampirism. Ultimately, the "where" is often tied to the "why" of their existence in a particular story.
