Ancient Egyptians called that sort of thing "Ba" and "Ka"... That sort of thing generally provided ancients with the functions which cell phones and things like gotomeeting.com provide us with today but, by the time of Christ, a number of centuries had passed without anything like that being seen and people were turning into atheists and evolosers. The best place to start on the topic is Julian Jaynes "Origin of Consciousness", at least as to how the thing worked. Jaynes of course viewed what he termed 'bicameral' phenomena as 'auditory hallucinations' of course since he lived in an atheist/evoloser academic world; nonetheless as the original post here notes, there is sufficient historical evidence to view such phenomena as real.
I don’t see any connection whatsoever between my question and your “answer”. “Ba” and “Ka” refer to noncorporeal entities (”soul”). In Jesus’ case the body was definitely physical, not ethereal. So I ask again, how would the Romans have caught, held, and re-cruficied a body that could simply disappear out of their hands and appear elsewhere???
