Not really. I understand what you are talking about, but what should be remembered about ideas is that they are, at least, bound to be earthly - and they always will be. Ideas are independent in the way that they represent the essence of entities, and that representation is - at least in our reality - eternal. But the problem is that even though ideas exist unbound of the reality itself, independent in some way since they aren't present in matter, do understand that ideas are describing the reality, space and time. No matter how "freely" you think, they derive from our world and their truth is not blurred, but a manifested vision - like a simple rectangle in a world without shapes. What you must understand is that the world outside space & time is indefinitive, nonexistant, eternal and omnipresent. The self is only bound there through the exhale of death where we become one with nothing; and by then, the self isn't independent, for obvious reasons. Nothing can be independent in a world where that nothing doesn't even exist.
