Except that's exactly how it works. I've looked into and actively engaged with all the topics you've talked about in the past, it still doesn't convince me that there's fundamentally anything after life. I won't say there's nothing, I'm agnostic, but I'm not convinced we're bound to return to some greater celestial being. There does have to be a first mover, whether that's the big bang, God, or some other cosmic entity, there is a first mover. A point where nothing existed before it and it somehow came into existence, or that everything has always existed and the expansion simply happened because it did. But just because there has to exist a first mover does not mean it automatically validates spirituality.
To be clear, I'm not saying belief in the supernatural or paranormal is wrong, but I do think fallacious arguments used to defend it, similar to arguments used by iron-clad athiests as if they can proclaim that there is nothing out there when we truly don't know, are misguided at best and downright deceptive/manipulative at worst.
Well, its clear to me you did not research enough or you were so close minded you didn't see it.
This is the framework by which you can validate each of those topics I mentioned against:
You are not the body, but the awareness. Consciousness. You are not here for learning. Your not here for "spiritual growth." You are already everything. Instead, you are here to have an experience, of forgetting that you are God. You are currently experiencing this body. When you have dreams, you are exploring IN another body. It can be as stable as this reality here -- or it can be unstable. You could peek into the future of this path you are in -- that's how you get dreams that predict the future. In the dream, the dream appears objective to you, right? Because you are experiencing it from that body. This world appears subjective. Come back here, to waking reality, and your dreams appear subjective.
How does it work -- think of an infinite universe, everything already exists. An infinite fractal. All moments. Everything that could happen. Your past, your future. Your awareness is going through each of these "reality spheres." They are like frozen moments, a picture. Each one contains the entire universe. The body is inseparable from the world it is in. Your consciousness/awareness simply travels to a location in the fractal where the body and the universe happens to be in that state. You are going through the reality spheres right now, by where your awareness is focusing. Where you focus, that's where you go. As you experience time, that's you going through them. That's why some people say "you" are the television screen, and what's playing on the screen is your ego, your character you are playing here. The real you can never be hurt or die.
So, all of your past moments of "this character" exist, and you COULD -- you, as in your awareness, not your character, go BACK in time and even experience that over again. Or you could go to the future. Or you could go into a fictional story.
And like Yogih said, you can also add synchronicities.They are also a part of a fractal, and fractals will always have synchronicities. Signs.
--------------------
Remote Viewing, Astral Projection/OBEs, Near Death Experiences -> Rejection of Materialism -- you are not in the brain.
Psychdellics, Meditation/Advanced Meditation (Gateway Tapes / Binaural Beats) ->You are not JUST this body. You are everything. If you read high dose LSD/DMT reports or salvia reports, you will find they often explore in another body. There are many people who have had such experiences.
Quantum Immortality, Mandella Effects, Synchronicities -> These three show the fractal nature of reality, that you are merely an awareness exploring a story. If you research QIM you will find many people report experiences of dying, like in a car crash, then going back to a moment before where there is for instance slightly altered things in their reality. Synchronicities are signs that appear in the fractal. As for mandella effects, they are signs that where you were exploring previously in the fractal had something different than where you are exploring right now. Maybe then Pikachu had a black bit on the end, now he doesn't.
Magic/Witchcraft, Energy Work/Chakras, Lucid Dreaming, Reality Shifting -> Evidence of people's ability as awareness to alter their reality. You can do it on psychdellics/meditation too. Witchcraft exists. Do you think all the witches are playing play-a-witch? lol. As does energy work, chakras. Lucid dreaming, you are actually going to another body. Reality shifting is you going to a reality like ours that is just as real where there is a lot of consciousness (energy) compared to dreams. There are many people who claim to do this also.
--------------------
Start with remote viewing. If you actually research this seriously, you will find out that you as consciousness are not limited to this body. You can peek anywhere, find information non-local to you, from the past, or from the future. This will start one's rejection of materialism. Listen to Alan Watts. If you are not willing to accept this, then you will just find any reason to deny it.
I have always been a spiritual person but also born a muslim, I belief this too, but it makes things so much more conflicting with the beliefs I grew up in. I anyhow experienced dreams predicting the future, I am still somewhat scared of the afterlife even with these realizations I got over the years, especially considering if I were to CBT, it's in the lowest of the lowest states I have ever been in. And I think that also has an impact on one's crossing over.
Add synchronicities to this, thinking of someone, them suddenly messaging you etc etc, we're in constant telepathic communication with one another. One doesn't have to belief this, it's the truth. If you know ya know, so many more things really that we can't fathom with our minds, it's only when you get these realizations through lived experiences that you really start to realize whats up
Read my comment above. You are better off letting go of the baggage of all religions. All of them try to make sense of God, but they can't. Because their purpose is to control humans. Does it make any sense for a loving "God" to put a muslim in hell just because they happened to be born muslim instead of christian? what if the muslim happened to have much better morals? Its pure hypocrisy, and it applies to Islam too. If your interested, try psychdellics. With meditation on psychdellics in pursuit of ego death / letting go of all your attachments, you will get closer to the truth.
