Well I mean...science doesn't support this belief. What people have faith in is no bother to me, but there is simply no evidence to suggest that energy somehow becomes non-neutral by flowing through a brain (also, that doesn't seem to make sense because we're not reusing the same energy to do so, so if energy is tofu, it doesn't have long to acquire someone's flavor), that there is "residual energy" as such, that consciousness could be carried on that energy in any level, let alone reconstruct an entire body. And I can't think of any sense in which science is supporting some sort of connected life -- in terms of the building blocks of everything (energy/matter), we all share the same resources, but that isn't exactly cutting edge research. So I guess if you can't construct an argument of how science supports this, why try to bring science into it at all? Talking about "energy" in a vague sense is about as scientific as Buddhism.
