This is interesting, but the possible existence of the soul, based on this evidence has nothing to do with whether our universe is a hologram, artificial or not. Careful 'arguing from ignorance' to explain the unknown.

Your argument is 'arguing from ignorance' that claims, because we cannot at present explain a phenomenon therefore . . .
Nonetheless this does not address the issue of holography and the nature of the universe, and the question as to whether our physical existence is an illusion.
