À very interesting questions. I've long felt there was two possible answers to this. You can see a more complex layer at the level of the relationship we have with other beings or even objects (Me + My Favorite Song would be a being of n+1 level of complexity). I call it the Deleuze/Spinoza hypothesis.
Then, you could see it as a kind of personal truth you're embodying, not as a creator but just as an operator, a tool. Although "personal" wouldn't be the right word. You would embody, express, a fraction of a deep truth which is specific to each being.
Or maybe something else I'm unable to imagine.
Also, if I may add and as other have stated, some do not see consciousness as the most complex layer of the human being. Some even consider it as an off-product of our highest functions.
