How to select which supernatural to believe?

[Belacqua]

...perception still goes a long way, depending on how you frame things.

Yes, I think the way you describe it is exactly right. 

Wish fulfillment, and finding excuses for justifying the things we want to believe. I suppose we all do it in a way. 

I don't believe there's a hidden world that decides what card comes up next, or any of those magic methods. 

At best, I think tarot or something like that can prompt us to think about things that otherwise might not occur to us clearly. The cards in the deck are designed to provoke associations of ideas and give our feelings some form that we can then think about. I've heard Freudians say this about dreams -- the dream itself has no meaning, but how you interpret the dream afterward says a lot.

I do think the subconscious mind is full and active, and it's hard to put it into some kind of order so that we can start to deal with it. Having certain symbols to hang on to allows us to clarify our own minds. 

The trouble of course is that some sets of symbols are better than others. And propagandists or other people with an agenda know how to manipulate our confusion to their own ends. 

Without agreeing that all that stuff comes from the devil, I agree that it might be wise to avoid a lot of it. At best it's organizing what's already in the mind, but (as you know) it's also used to scam people and propagandize, and we get enough of that without going to fortune tellers, too. 

Great literature can provide symbols we can hook on to and reveal our unconscious minds to ourselves, in a much richer way than some palm reader can.
