Nice post, but can you really wonder if 'death' is the last outpost of life?
Science may correlate with religion in-as-much as what lays beyond our mortal being giving up the ghost when death occurs, all due to atomic physics and the descending apparatus that constructs an atom, but can it really identify what those parts are that make up the whole?
There seems to be 'something' that is ever elusive, for religion and toward science, because electromagnetism in its ever simplest ways proceeds and pervades all. We know what a quanta is, and know that it is a little packet of energy that is composed of its own parts to construct a quanta as a whole...but parts maybe the elusive wonder: 4 parts of the whole makes 'something' while three parts just misses out.
It seems that no matter what we can construct to invade the subtleties of the atom and its parts, we only ever identify 'substance'. While 'energy' jets around that substance...exists because of that substance...and may be observed if that 'substance' is trapped in a moment and explored, we end up with the 'unknown' within both the substance and the energy.
We don't have the apparatus to delve into that yet...what lays within 'energy' when one part of a quanta is trapped and exploded and explored...but we do have a mental exploration first...have had it for millennia as evidenced by certain burial practices...folk like to invest paraphernalia into graves because the dead may 'want them' afterwards.
If it comes down to why paraphernalia is put into a grave, to appease the dead, then dreams are the culprit to entice such a practice in order to appease the minds of the living and the dead.
And then we get into 'where do dreams come from?'
It seems that energy exists far beyond our scope to thus-far understand, in all its parameters. And may actually settle itself 'somewhere' even beyond dreams...beyond science and religion and wonder. Not as something that can be grasped but as something that is like a certain scent of a flower on the wind while walking through a vast forest.
It may depend on which way the wind blows to direct one to the source. And anyone is able to experience that...if we but 'smell'
