You can think this all you like, but it remains logically absurd. The exact same laws of physics (and metaphysics) apply to our internal phenomenology as to any effecting eternal phenomenology. So to claim that the internal phenomenology is somehow 'less valid' than the external phenomenology is simply illogical. It's all of the same phenomenology.
It is quite clear that the exact same laws do NOT apply in both cases. I can, for example, easily imagine that gravity does not exist.
If you mean that the same laws apply to our *brains*, then I agree. But that is a very different thing.
And, yes, internal phenomenology is less valid that external. We know that because of the numerous contradictions and illusions given by our senses and mistakes made in our thought processes.
The sun shines down on a three-dimensional tree, casting a two-dimensional shadow of the tree on the ground. Do you think the two-dimensional shadow is somehow less 'real', or less 'valid' than the sun and the tree? Yet this is what you appear to be trying to claim about the idea of a tree in the human mind.
Yes, the shadows is less real. it is simply the relative absence of light, as opposed to something physical and separate.
And yes, I apply the same to the idea of a tree in my mind. it is not the same as the tree outside of my mind.
The human imagination is 'real' And so is what it imagines. The difference is that it's metaphysical reality as opposed to physical reality. And it's that materialist bias against metaphysics that your mind will not let go of.
Yes, I agree. Most metaphysics is pretty bad philosophy. I don't think there is anything that does not supervene on the physical.
