Matter IS energy. Or rather, matter is one of the ways that energy is expressing itself. As are space, motion, time, light, heat, attraction, repulsion, and so on. These are all "physical" expressions/manifestation of energy. Unfortunately, we have no idea what 'energy' actually is, from where it originated, how, and why (if that question is even applicable).
Life, consciousness, and finally cognition (conscious awareness coupled with imagination and reason) originate from, but are transcendent of, the physical realm of existence. "Transcendent of", in the sense that they open up a whole new set of existential possibilities that did not otherwise exist in the physical realm from which they originated. I would refer to this, then, as a "metaphysical" realm of existence. It is not separate from, but it is distinct from, the realm of existential physicality.
Reality, then, (by my understanding) is a metaphysical cognitive reflection of the physical realm in which we humans exist, as generated from our limited sensual and intellectual experiences interacting within it.
As we experience it, yes. But our experience of existence is very limited, as is our ability to understand that experience. So the further existential possibilities are limitless (from our perspective).
Yes. Or more. We do not know. I would offer one more 'aspect' of existence: that of the "Divine Realm". That being the realm of existence wherein the great mystery of it's being is resolved. And I would include it based on the fact of our being able to cognate the questions of existential origin, sustenance, and purpose, but not the answers. This, to me, hints at another 'transcendent' realm of existence, beyond the physical, and the metaphysical, within which these 'answers' are to be found.
