The not-quite departed don't want to haunt our houses so much as our thoughts.
Truth be told, haunting is a pretty compelling explanation for the Easter story. If you're so inclined, of course. You have the prerequisite geology angle with the stone tomb, the fear and guilt Jesus' followers felt making them more receptive to spectral influence, the conflicting stories, the violations of the laws of physics. Throw in some dreams, visions and fantasies and you can wrap that thing up with a bow.
But again, that's not the selling point here. Because the pitch was that if you believed this story, your dead sons would one day return to you too. And for most of human history pretty much every family in Christendom - the world- were pining for a dead son.
I think this is a self-correcting dilemma. Trauma will inevitably lead people away from secularism- to religion, to magic, the New Age, whatever. This in turn will have a knock-on effect for the rest of the culture.
