My theory:
Quantum decoherence is the mechanism by which quantum systems interact with their environments to exhibit probabilistically additive behavior and give the appearance of wave function collapse. If the wave function merely encodes an observer's knowledge of the universe then the wave function collapse corresponds to the receipt of new information.
Because our thoughts are quantum systems this means our aura is a quantum system.
I consider a wave function with n=7 states from our aura.
Because our aura is around us that wave function is collapsed in the state ІΦi > . where i=3.
When people have near-death experience the aura will not be around the body; they will experience pleasant emotions; calmness and serenity and this wave function will have all 7 states, each ІΦi > state with values λi,
I consider the state 7 the ‘highest’, closer to God.
The aura is coming back near the body because meeting deceased relatives or spiritual figures they will tell to the person to go back.
The person will go back in my view because of this command ‘go back’ a thought who is a quantum system who will collapse our wave function. The wave function will collapse in the new state 4, a higher state than 3 how was before NDE. After NDE people are saying I’m a better person, was wonderful there…For them the values for λi during NDE where i=5,6,7 had a high value; they experienced mostly the states 5,6 and 7.
15% has bad experiences during NDE this means for them the values for λi where i=1 or 2 had a high value; they experienced mostly the states 1 and 2 and of course they will come back in the same state 3.
Are 7 states because are 7 major chakras or energy centers. We are thinking with the whole body, with all our cells in the same time. When you are angry and you will send out an angry thought, all the cells in your body will lose energy.
After so many years I found the solution for this chord (it is on my website too):
The chord of each man is unique, and whether he be sleeping or waking, living or dead, his chord is always the same, and he can always be found by it.
If the states ІΦi > have distinct, definite values, λi, of some dynamical variable and a measurement of that variable is performed on a system in the state
Іψ> = Σ ci І Φi >
then the probability of measuring λi is | ci | 2, and if the measurement yields λi, the system is left in the state ІΦi > .
Are 7 states ІΦi > because are 7 major chakras or energy centers:
Іψ> = Σ ci І Φi >
ψ is the wave function of each man, the unique chord whether he be sleeping or waking, living or dead and he can always be found by it.
How I calculated 97.73% are in the states 1 or 2 or 3 and 0.077% are in the state 7 the God state. (The probability to find a person in state 7 is very small).
