Not really? But our ghosts aren't usually like the movies? I guess? I haven't watched any movies, so I'm not sure I'm an authority. The souls that crowd the Underworld can be a little scary, I guess, but mostly it's just sad because you know they don't have the fare to get across to the Underworld. Even if it's only Asphodel that they end up. And that's also not scary, but sad. They don't remember who they were or what their lives were and they never change. But they can't be sad because they don't even know to be sad.
