Essentially, I speculate that there is a constant "leaking" of information from one universe to another, and that the more similar the universes are the more "leakage" there is between them, very different universes that have had very different events (like, say, universes that went their separate ways at the Big Bang) will have virtually no leaking of information between each other (the technical physics term is Decoherence)
I also speculate that living things with nervous systems have evolved mechanisms to filter out much this leaking to prevent unnecessary reactions that would imperil the survival of the organism, If you are an antelope trying to avoid lions in your own universe reacting to ghostly images of a lion leaking in from a similar universe isn't going to help you, and it will certainly distract you. But, this filtering is not 100% effective, and some people are more sensitive to the leaking than others. I also suspect that the immature brains of young children are less good at filtering than the brains of adult individuals are.
You have probably already guessed where I'm going with this. I suggest that this quantum leaking is the source of a lot of "paranormal" stuff. I speculate that ghosts, for example, are the result of information leaking in from a very similar universe where the deceased individual is still alive. This would explain why most ghosts don't exist for a long time, eventually decoherence eliminates them.
Have you read Neil Stephenson's "Anathem"? Not to hand you any spoilers, mind you, but .... just read it.
How to spot a shill, by John Michael Greer: "What you watch for is (a) a brand new commenter who (b) has nothing to say about the topic under discussion but (c) trots out a smoothly written opinion piece that (d) hits all the standard talking points currently being used by a specific political or corporate interest, while (e) avoiding any other points anyone else has made on that subject."
