It requires a peculiar stretching of the term consciousness to say that that is what you are, to identify it with being. Insomnia offers a stark example in which consciousness is stuck in a state of activation while you want only to be rid of it so that you can re-submerge all experiencing into the primal blackness of being, namely dreamless sleep. Of course you could say that this is about different modalities of consciousness but this is to deprive the term 'unconsciousness' of any meaning. Consciousness is something you have, with its qualia and its 'what it feels like'-ness, and while it is a metaphysical mystery, the self, the 'i' is a different and deeper mystery, which is more than metaphysical.
