User blog:KillRoy231/Souls ceasing to exist?

Something has always bugged me about any shows where someone's soul is erased and they're completely nonexistent.

Example being anyone who dies after their soul is eaten by Amara. Or anyone who dies after being kissed by a Dementor in Harry Potter. Or anyone shot by the Godkiller in Drive Angry. Or in Dragonball Z if you die when you're already dead. Or if time is altered and you're never born? Or even being frozen in time for eternity (because they're not conscious for any of it), like the shadow half of the Pony of Shadows in MLP.

What is their eternity for them?

Typically, if you die you go to heaven or hell, or some afterlife, your soul usually cannot be erased. But, obviously sometimes it can. This seemed as good a place as any to ask it as it's confirmed Donatello's soul was destroyed when Amara ate it, even though he's not dead. At least not in body. But at least two of Amara's victims are.

So, what is an eternity of utter nonexistence like? Endless black, no body, no memories, anything? Or maybe some sort of eternal dream? The answer that makes the most sense is not being conscious of anything for eternity, but then what is that eternity for you?

On that note, do the dead angels and demons dream when they're asleep in the Empty, or are they effectively in an eternal unconscious sleep that's similar to the Pony of Shadows scenario (though they ARE definitely dead in this case)?

I don't know, it gives me a headache to think about.
