Yes, I know that it is the law of Conservation of Energy. I study physics. As far as the type of energy that I am referring to, we have electricity in our bodies in our nervous systems including in our brains and within our hearts. Our hearts are powered by electrical energy.
So you know how when you cut off the source of the electricity to a light, the light goes out, right? The same basic principle applies. It's not that the electrical energy has changed form into some ectoplasmic electricity that goes off into some mystery realm. It's that there simply isn't any of it there anymore. The circuit is "dead".
Additionally, we and everything we can see and experience is a collection of atoms. Atoms are made up of particles. Most of those particles are energy. Only one that I know of, the Higgs Boson, is matter. More may be discovered in the future. I am speaking of the energy particles of atoms. After all, physicists have discovered that with quantum entanglement, atoms can remain connected over very long distances. Additionally, in the double slit experiment, it was found that when people view atoms, they change the paths of those atoms.
Those are loosely related concepts that have no bearing on the possibility of an afterlife.
Basically, what I am saying is that there is energy at an atomic level within human bodies. That does not disappear when someone dies. So, what happens to it? Is it just simply dispersed or does it maintain structure as with physical bodies, trees, rocks and other objects to create forms?
What happens to the energy within the materials that makeup our bodies after we die depends on a variety of environmental and chemical variables. These are very basic concepts that anyone with a grade-school level education would ( or at least should ) understand, and they have nothing to do with afterlives.
Does that remain after death? Does anyone have any idea about this?
Yes scientists have a really good idea about that.
I haven't seen any scientific journal articles reporting that physicists have proven what does occur to energy following the death of an individual. I do monitor several physics journals for new discoveries.
You don't need a science journal to work it out. Like I said before, a common form of energy produced by the human body is heat. Upon death, the processes in our bodies that create heat stop functioning, and if the temperature of the environment is lower than that of the body, the body begins to cool toward a thermal equilibrium with the environment.
Personally I find this all a bit morbid, but there's plenty of studies out there. Maybe start here:

These are really basic concepts. There is no magical afterplace where the heat from dead people goes, and heat is not in and of itself a living thing, other than perhaps in an allegorical sense e.g. "If the fire is still alive, don't forget to kill it before leaving your campsite." I'm really sorry if these truths conflict with your ideas about afterlives, but don't you think it's better to know them than believe in nonsense?
NOTE: This isn't to say that I don't believe strange things happen ( they do ), and we don't always have a scientific explanation, but that doesn't mean we should jump to the first available alternative explanation either. If your personal experiences are out of the ordinary and important to you, by all means, explore them.
Just don't settle for easy popular answers unless the evidence supports it, and trust me, in the case of afterlives, reincarnation, and other similar notions, there is no substantial reasoning or evidence to believe any of it is what people typically interpret it to be. At best, any unexplained memory is only some sort of acquisition of information. You still remain you, a unique individual in the history of the universe, not some reconstituted dead person.
