Energy transformation in my opinion. I believe once the body's brain loses the quantum state and does not recover, the energy that was used dissipates. This energy can manifest through memory as the pure energy form of its memory. The cell memory energy is responsible for manifesting the energy of the cells with memory driving how they manifest. With humans this would be human cell energy and memory. This would produce a pure energy form of that memory or "spirit".

We now drive biological entities that create these memories stored as energy. We only have the amount of energy for that purpose therefore we must feed the biological part to sustain the extra energy required. When we can no longer sustain this, we lose the biological entity and return to pure form with new memories equalling more energy than we started with.

We can't see an unborn persons spirit because it has no memories to manifest.

Interesting thoughts Travis. Mine are similar but with some key differences.

The question of life after death has intrigued me for the longest time and one I've always been extremely curious to find the answer to. I didn't think it was possible to get a definitive answer (and in some ways still don't) but to me the best evidence for a yes or no answer comes from studying paranormal phenomena like the near-death experience (NDE).

To take a step back, modern science would have us believe that everything is physical, that all experience and reality, at a fundamental level, are tiny electrons/protons/neutrons and even tinier quarks/leptons/bosons/etc...This is an assumption of course, because there may be things even more fundamental that we cannot detect like say consciousness or mind or spirit, for example. Modern science would also have us believe that the human brain is responsible for consciousness, so once that goes, so does our experience and our 'self'. Citing examples of people with brain damage and having corresponding deficiencies in experience and ability, based on the location of the damage, seem compelling to argue for this theory. However, correlation does not imply causation, and therefore it is merely a good assumption.

I prefer to think of the analogy of the brain being equivalent to a radio. The radio can receive signals and broadcast them to be experienced, but the radio is not producing the signal and subsequent audio transmission. If, say, the radio falls and gets damaged, perhaps a range of frequency will be lost or the radio can no longer play as loudly. The signal is fine but the receiver/transmitter is not. Same can be true of consciousness. It may be fine and intact but the body with which it experiences life on Earth / this reality is dying or dead. I think at that point consciousness moves on to another realm, one where the limitations of a physical world are no longer present.

I base this on researching NDEs and related phenomena. I won't go into fine detail due to time constraints, but the basic idea is that there are times when people have these experiences of being very close to death or clinically dead, get resuscitated, then tell of their experience with elements that can be corroborated by hospital staff (as these typically take place in a hospital) and/or relatives in the nearby vicinity. There are many cases of this happening and each case needs to be investigated and evaluated separately, but having read probably at least 100-200 cases, I feel confident that there is something to them and it's not all a fluke or fraud or something else.

I don't expect people to believe it based on what I have said, nor would I want anyone to really. I would hope people investigate it for themselves to see if there is merit because if there is, the conclusions would be life-changing. Some suggested readings to start would be these books:

That is good perspective to take on the subject. One thing I disagree with now is that only human consciousness creates our world. I believe everything that is alive is conscious, including plants, adding another dimension to what consciousness is. To me it is a product of intelligent energy that through time collectively changes its environment through observation.

Most of this falls back to physics. We know observation changes outcome. Plants, single celled organisms also are aware of their surroundings and adapt as needed. Our physical world, if built from observation and memories of these observations as physics suggests, may have started from a quark needing a boson to take a first step to create its ideal environment. It doesn't know nor do we that. The boson does the same and collectively start building their physical world through energy manifestation of their limited conciousness.

Humans are much more complicated and everything from the universes quarks to us build upon collective consciousness to create a balanced perceivable world. At the same time all these observations change their environment subtley as they improve their own environment. But, one improvement by one would effect another in turn effecting its observation in turn effecting how it changes what its ideal environment is. This cycle makes sense to me as it compounds greatly as intelligence is forced upon everything, using memory as a guide to not make negative changes that would effect its survivability.

I will have to learn more of NDE. But from what I do know, I believe our known consciousness (self awareness etc) is similar to a computer. While it is on and running, we use our senses (input devices) to perceive our environment. When we die or shut off the computer we see a flash of light as the energy field that drives the device (body) collapses. The energy is still there and available but no longer used for that purpose.

So basically, I don't believe consciousness is merely a human experience but rather collective. That said the paranormal side to me is a manifestation of memory and has no conscious effect as it no more than memory although it can effect other entities like humans that can change the perceivable world.

Could add more, feel free to ask questions as I got busy and distracted during this post so I hope it even makes sense in some way lol.
