If this other worldly whatever determines how things look and work out in physical reality then it is interacting with physical reality
I wouldn't say it's interacting with it. Example: we know that gravity exists, we know how gravity works, but we don't know WHY it exists. We don't know what gravity "means". That other world gives us an answer to the why. Science gives an answer to the how.
The other world is static, this one is dynamic. (Or perhaps the other one has a much higher inertia than this one.)
its still having an effect on our reality
If "having an effect" means a cause-and-effect relationship in time (cause first, effect second), then no. Things play out in this reality because of how things are arranged in that other, but there is no direct cause-and-effect relationship. The other world is the blueprint, this one is the manifestation. The two are inseparable.
So where is this evidence for this nonphysical reality?
The only way to gather such evidence would be to invent a method with which we could alter the structure of that other world (the world of blueprints) and then observe the resulting changes in our world.
If we could repeatedly do this, that could serve as a source of the required evidence.
As I currently don't know of any such method, from a scientific point of view, my theory is nothing.
Note that what I mean by physical reality I mean all matter and energy even forms we don't yet know what they are composed of.
And by the "idea world" or the "world of blueprints" I mean an abstract world - much like the world of mathematics - which determines the structural and behavioral patterns of physical reality.
I don't see how patterns from another world manifest themselves as fear in everyones thought patterns. That makes no sense.
Sorry for this part, I see your problem. Forget it.
The world is not a life form.
Why are you so sure?
Imagining the world (our Earth, to be more precise) as a life-form is of great value: we can relate to it as we would to another human being. If people cannot connect to the Earth, if all they see is a lump of matter then it may be harder for them to realize why it's important to take care of "Her".
I think that nobody came up with any evidence to support your claim (that the world is not a life form). Therefore I am free to believe it is (that it has extra "layers" beyond those currently observed by science). And if this has a positive effect on my life, I prefer this belief to that which states it's just matter.
(This same argument may be used regarding the existence of God.)
Ideas don't come from some alternate reality they come from our minds.
Yes they come from our minds, but we are able to conceive them because they are in that alternate reality as blueprints.
If they were not present as blueprints, they would be unthinkable. They wouldn't exist.
The blueprints make it possible that two humans can think of the same idea. The blueprint is manifesting in two minds at the same time.
Without the blueprints, we could never be sure that we can really share an experience. We would be alone.
There is lots of evidence for that claim but none for yours so why do you think its so important?
Because it gives depth and meaning to my life.
I wouldn't believe in such things if there were any evidence against them, but fortunately there cannot be.
I also don't see why you are saying a materialistic view is like a prison.
It's only a prison if it closes down. If it stops allowing other possibilities. If it doesn't want to face new facts, because it's sure everything is already known.
It's the same difference as between "atheism" and "agnosticism".
