Intellectually the leap to believing in ghosts at all is longer than the mere stutter step to believing then in ghosts' apparel, ghastly accoutrements, and ethereal monocles.

But surely an identity would need to projected onto a ghost to transform it from an unknown haunting in a sheet into a known phantasm recognized by its victim.

Like dimensional digital projectors from our soul or collective consciences onto the sheet to create a ghost seems to be the idea.

Hmm, maybe we can think about it like a "reverse" "residual self-image" from The Matrix. The "ghost" doesn't have a form, but it's interpreted by our brains based on various energy signatures.

But then again, that's all matter (well, waves), isn't it?

Now that everyone has cameras on them 24/7 we should see an explosion of ghosts reports if ghosts are indeed a thing. Is there any data about such thing?

More people have died in the last 50 years than in the last 150 before that. The ghosts should be modern, with tape decks or pinwheel hats and mullets.
