Excuse me but what the actual fuck?
Disguised ghosts? What? Who are they trying to trick?
This one makes no sense, now the FMC will be overly cautious of everything? This is straight up paranoia and I don't like that, if the MC is not mentally stable then we might get "distorted" version of reality without being able to tell what is what and That is harmful to a storytelling if I may say.
But nevermind me, that might be deeper that just an unexpected fluke, time will show.
