@Leadfoot,
I guess it was this that led me to think you believed in some kind of supernatural. If you think they are 'involved' then they/it must exist.
But in view of your later statements, I assume you must mean the supernatural only exists in the imagination.
Sorry, I didn't make myself clear, I meant that what we call the supernatural is included in what we reify. So, we can have a conversation with ourselves or with an imaginary person.
Now, I am not saying that when it pertains to the supernatural, that, to the person, it is the same as talking to oneself or what we we call an "imaginary friend" (although depending on the depth, it could be).
While I believe that the underpinning for the two is the same (hence super-naturalism is contained under the general cause - or one of the causes) 'on the ground' as it were, to the person experiencing these things, they can be percepted quite differently.
Without going into massive detail, (mostly because I don't know all the details!), one of the differences is the emotional 'tags' that come along with religions apparently inevitable sidekick: morality.
These things are also contained under the idea of polymorphous perversion - our ability to love anything (animate, biologic, inanimate objects). Precisely we do this because of reification. We can love someone that we have never met, never talked to, don't even really know, except their name if someone told us that they did something wonderful for us and we happen to believe it (for whatever reasons).
If this was believed, it wouldn't take much of a thought experiment to know that when we met them, there would be an actual, real, 'tangible' emotional connection to that person. Firefighters save unconscious people and when those saved people meet their benefactor..
Those are powerful emotions that stir within us and as un-nuanced as I was in my example, apply aptly to religion. So, these things are real to us. The moral dimension is especially powerful and, I believe, while reification is the engine, morality is the fuel that makes religion go. It is hard to conceive of religion without it. In fact the bible makes this explicit when James reprimanded Paul for his insistence that faith alone saves.
So, yes, in the imagination, that's where most likely exists, but, it is
real to us..
