Hi, I've been to different resources and forums where this was discussed. Here is one interesting story of a guy (it looks like a fantasy, but these are his words)
"I have been a trusting child since my early childhood, and one day I was told that by tearing off a leaf and tearing off a piece of it, you can avoid death and return to that moment, which is what I started doing. At one point, I, being a 7-year-old boy, fell from a hill with my head on a stone, because of which I should have died, but only after the inevitable darkness I found myself at the moment when I threw out a leaf, then I did not really understand and considered everything that was happening a dream, but I did not go to that hill anymore because I felt an instinctive fear of it, after that I forgot about this feature but continued to tear off leaves, this was until I cut my throat at the age of 14 because of bullying at school, when I also that time instead of death opened my eyes at the moment of throwing out a leaf I understood everything. And immediately went to make money, saved, remembered the outcomes on bets and again cut his throat, only instead of winning I got nonsense, because the results of the matches changed. In addition, in the photo where I was with my family and who instead of a Sim cat had a damn Labrador, and when I asked my parents about this, they twirled their fingers at their temples and began to assure that we never had cats. Around the same time, I came across one of the videos about quantum immortality" and the corresponding thought experiment that seemed to me to explain what was happening to me, and I finally understood that after death, a person decides with his own faith where he will end up, if he believes that he will go to heaven, he will end up in heaven. The world of one piece - in the world of this anime, etc. I tried to change my faith, but everything went extremely badly, I still rolled back in time and space, apparently to another version of reality. How long this will last - I don't know, in any case, I don't care about it anymore. It is impossible to return to the original reality. You can only accidentally (or consciously) get into a reality where your physical body (at the level of neurons in the brain) remembers what happened to you (with its old memory). If a person does not believe in anything, the memory will be erased and the observer will again begin to observe from a clean slate." This anonymous person also said funny things that sometimes change in other versions of reality (there are an infinite number of them, and in one there was no Australia) - in one, Hitler's Germany won (little changed), in another - there are a lot of people of a strange race - like black albinos, but with an admixture of Asian blood. But this, of course, looks just fantastic. More serious and real things happen in Tibet, as far as I know.
Personally, I asked myself this question, and came to the following: the entire material world consists of elementary particles - protons, neutrons, electrons (and, accordingly, those that are even smaller - quarks, gluons that bind them, etc.). These particles are the same everywhere, but their DISTRIBUTION gives such an effect that from one set gold is obtained, from another - a dog; from one - a tree, from another - a person; from one - water, from another - a stone. Now let's remember the fundamental law of nature - the law of conservation of energy: none of the types of energy disappears into nowhere and does not appear from nowhere, it only transforms from one type to another. According to this law, we are already immortal. It is only necessary to find the connection that will make a new product from our dead remains and elements. In ancient Greece, such a term was used: eidos. It meant the essence of a thing: the eidos of a person is humanity, of a stone - stoneness, of a horse - horseness. No matter how the elements are put together, they will give exactly this final product according to some law that a person does not yet know. This is the law of distribution of elementary particles - the particles are always the same, but they are put together in a different sequence and give a different product FOR SOME REASON I can only guess with an analogy: if a person needs a means of transportation on the sea, he makes a ship. Nature itself would not have given birth to this ship without a person. It is the same with everything that man has created: a machine, a computer, a wire - anything - these are just desires and embodiments of people. In the same way, other things are created, like wood, water and stone - these are desires and embodiments of something else. Our dead bodies (as well as electrical impulses in the brain (or what gives us the ability to think at all) - will not disappear anywhere. A certain law will simply group these particles into the object it needs. If you loved a certain person very much, or were close to him (friends), and he reciprocated - then, perhaps, these "impulses of love" after your death will gather together with his impulses, simply because they are somehow attracted, and this spark of thought created by the two of you, hovering in the air forever, will one day come to a certain person, and he will experience the same thing that you experienced, but will not understand that these are not his thoughts - but the thoughts of long-lived people who have never left and will not leave this planet. His smile because of your long-standing feelings will be the final fruit of your existence in the world of people.
