Can brain frequency predict whether your plasma descends stays or ascends after the moment of death?

Now that we know the EMF frequency of the Earth is 783 hertz and the brain is usually at a similar wavelength does this mean that at lower hertz the plasma would sink below the various other waves in the air, if it was the same it would disperse in the air, and if it were higher it would rise and join the cosmic "void" (also plasma BTW) at the moment of death when this plasma leaves the body? If so, can we predict where it would be more likely to go for a given person? If yes, is this proof of a sort of "heaven" "purgatory" and "hell"?
