Piggy-backing off this question: Carlisle's curse has left him super attuned to the undead, including ghosts. He probably couldn't see them early on, but under regular circumstances, he'd be able to once they start gaining power, but before they're fully solid. In addition, he'd normally be able to sense their presence, even if he couldn't interact with them in any other way.

Would that all still work, or is this more of a "god-made ghosts, so it's a different case" situation?
