According to advice of parapsychologist Israel Levinshtein,
I began to study religious practice-meditation.
And once, involuntary, I felt that vibration waves came on my brain.
These waves caused vibration of all neutrons of my brain.
They started vibrating in the same phase,
with the same frequency that the last waves.
All the neutrons came to homogeneous “vacuum” state.
And then I saw “myself”, my spiritual essence.
I gazed and saw clean silver circle.
And I initially understood that this circle was my true “I”.
And this true “I” is eternal, unwounded, passionless,
spiritual, conscious, evolutionary.
It was so exactly, so clear, so real that then,
recollecting and telling someone about it,
I told him that it was “more real than I am talking to you”.
Most of all amazed me that my true “I” is passionless.
Because I am an emotional person.
How is that I am passionless? And I somehow mentally asked:
And what about love?" and mentally received the answer: “Way”.
When the vision of true “I” disappeared, the first thought came.
And this thought drove on all the neutrons of the brain,
having programmed them with one question: “how to explain it scientifically?”
And I became a slave of this question.
All my time was devoted to the search of the answer to this question.
Socratus.
Unfortunately I will stick to your first question:
I think your “true I” was your mental projection of yourself, the spirit of the mind so to speak. Feelings and emotions are not “real”, as they are not logical or scientific (wait, follow me here… you’ll see where I am getting at) and your “I” was only that part of the spirit. The thing is the body might be divided in 2 ways of thinking: “thinking with your head” and… you guessed it, “thinking with your heart”. If you’d get in touch with your emotions and feelings instead of your neurons you will probably see your true loving self but not an enlightened spiritual, evolved and “all-knowing” version of your “I”. I do think there are 2 "I"s inside each of us, a heart-I and a mind-I (no pun meant to the mind’s eye context 
). To me it looks like the predominant “I” in you, is your mental “I”. You have your emotional one as well but I think that this might prove you “think more with you head”, than your heart. Although I might be 101% wrong in this 
I wish you good luck in surpassing new limits and reaching new checkpoints on your spiritual journey, whichever one you may choose, mental or emotional
P.S. I might have digressed into a philosophical plane of thought, but to me this thread would look best there, instead of the Psycho forums
Socratus! That was an algorithm! A condition!
Conscious human memory access is limited but human memory is perfect.
I think I know what this is!
What the next step is!:
Remember the exact state of mind and the “Feeling” that you had at that time, place yourself in that again [to the best of your ability, and it will work even if you’re not feeling it strongly] and then, once in that state of mind–live. Make choices, form opinions, ask questions.
New states of being produce new actions and thoughts that were not yet possible.
“Higher states” are simply learning experiences, much like a technological paradigm shift–in that a more efficient way is found, though an old way worked well for so long.
You’ll have more “higher states” happen to you, I suppose, later on.
All of it is a learning process.

Russia. Podmoscowye.
Early in the morning, I go to some village.
Around me, there are forests and in front of me, there is a ravine.
I am delighted with the surrounding me silence and beauty.
Suddenly there came a vibration wave, captured the whole brain
and I saw that in front of me a noisy broad quick river (where is ravine now) flows.
Far off there is a forest. Ancient people exist from the forest and hurry to river.
To the right three people stand. Two of them are supporting a wounded man.
And who is on the left, is me. Big, strong. The skin of some animal covered my body.
With one hand, I supported the wounded and in the other, I hold a spear.
The vision was distinct and clear. Then vibrations and vision disappear.
Amazingly, I looked at the dry ravine and still heard the noise of the river.
Once, in my past life I was a man from the wild tribe.
Turkey. Pergamum.
Early morning. On a steep mountain, straight on,
I climb up to antique town Pergamum.
I have climbed.
The clouds flow under me and they close or open the modern downtown.
From one side, sun lights up beautiful antique town and from the other
side shadows of the clouds fly along the downtown.
Beautiful.
I saw white stoned destroyed temple of Zeus.
I entered and stood still. Suddenly a vibration wave came and captured the whole brain.
As if failed, I fell on the marble floor, began to cry in hysterics:
“Oh, Pergamum, oh, Pergamum, what they have done to you!”
Far in consciousness, I try to collect myself and say to myself:
“Stand up! You are not crazy.” I rise and wonder to what happened.
Again there comes a vibration wave and throws me on the floor.
Again, I cry in hysterics.
I come up with tears and it strikes me:
“Once I was the main priest of the temple of Zeus and I liked this town and this temple.”
Tibet. Lhasa.
In the early cold morning, I hurry to some monastery.
Easy Chinese sport slippers do not
protect feet from shrill cold of the ground.
And cold burns feet as hot stones.
I am walking amazingly.
Suddenly vibration waves appear and capture my brain.
I saw myself in the national Tibetan clothes.
I hurry somewhere, but I go under some angle to meet myself.
We have not confronted nearly with each other.
I was frightened. And from it vision and the vibrations have disappeared.
The vision was short, but long enough for me to understood that once, in my past life,
I was inhabitant of Tibet.
These facts from my life, certainly, are not the proof from the scientific point of view.
And it is correct.
These facts are true only for me.
These and other religious experiences have helped me
to understand sense of the formulas and laws of physics.
But you see not only I have gone through such facts.
There are a lot of such people. Such facts are fixed in many books.
Tribes and the ancient peoples, in the past and in the present,
trusted and trust in immortality of soul, in its ability to incarnation.
Therefore to neglect these facts is unnecessary.
But we will take other situation.
The scientists write about " virtual particles†and “virtual transformation ".
Nobody knows, what " a virtual particle " and " virtual transformation " are.
I shall remind what Feynman wrote:
"We are obliged to imagine, that our system has hardly moved, even if it really did not
move and was not so capable to move. We use small imagined movement to apply
a principle of energy conservation. "
Unless, is such explanation convincing?
Such explanation is not convincing.
Comparing these two situations, we can understand,
that there are sufficient bases to be surprised and to reflect.
Socratus.
By the way, taking into account a paradoxical situation
in quantum physics, Schrodinger, in one his letter, wrote:
" As though quantum theory did not become the theory
describing psychological processes ".
Probably, he has written it in a joke.
However this joke once again
emphasizes depth of unusual behaviour
micro particle describing by quantum theory.
