Not that it was intentional. But I could imagine a possible side effect/and yet another potential benefit of being a ghost would be having a lesser presence. There's a group of 7 people all trying to do things, the idea someone may get unintentionally ignored by characters trying to figure out how they're going to survive/live isn't entirely unlikely. Hell the lightning and rain could very well drown out our voices, especially when we go into the storm. Just something to keep in mind/think about.
