Just trying to elaborate some here, so you have clear idea of what is going on. Awareness exists as it is completely independent of any other components so that no matter where you are, you are still there. You can't go anywhere or lose any body and not exist anymore...that's not how this works unfortunately.
Once God desired to send your soul into creation apart from Itself to experience life, God wrapped your conscious soul in layers to confine you to locations in creation. These layers include the etheric layer (intuition), the mental layer (mental), the causal layer (memory), the astral layer (emotion) and finally you were given a physical body (senses/physical perception).
As you leave each layer of form or covering you are present within that corresponding plane of existence. Yes, that means there are several parallel layers of existence cut out as individual universes which are known as the multiverse hypothesis. These preceding worlds are known as the afterlife, the spiritual domains but they are just parallel worlds. So that means that there is an etheric universe, a purely mental universe, a causal plane, an astral dimension and finally a physical universe which is the outermost layer.
If you were to leave each layer starting with the physical you would literally experience everything you thought was forwardly orderly, as reverse lol, materialists have it all azz backwards, it starts with consciousness, then to the mind, then to the emotions and finally to the physical experience sense perception. You would start with the physical experience and observe preceding levels in order as I presented them. This renders the physical layer as the least consequential in the reality of what you are.
As you are present within one of these corresponding universes outside the physical layer the dynamics of what you can experience is dramatically different because the laws of physics change, each layer is less restricted by the restraints of physical laws because of the properties of what makes up your external experiences. This is why when souls leave the physical body they report themselves as "floating" or hovering, that's due to the lightness of the spirit body. When you get to the mental worlds, you literally experience everything through thought without having the limits of the physical and astral body. You do suffer the limits and consequence of the mind though, which is why you can't enter these worlds until one learns the destructive nature of the mind and thoughts.
The fun part is when you get to the pure conscious realms, even these are independent of the mind and you experience everything by intuition alone. Your experience becomes created through dream-like qualities, which is wonderfully creative and blissful yet also very dangerous. Only souls who have learned complete discipline and control can enter such realms of existence.
Anyway, before I get too far into this just consider that the order in which you perceive to be the order in which you exist, is actually the opposite. It should instinctively resonate with you if you set aside your preconceived ideas. Creation can get really fun, but the physical world is but a flick in time compared to what you will experience on your journey.
And yes, that means that your spirit body, your astral body will exist much longer than the physical body due to the ratio of matter vs prana. Which is cool because the astral world, which most souls think is heaven, is astoundingly beautiful and far less inhibiting. The planets that exist in the afterlife and the places within them are unimaginably wonderful.
