Could a "liberated" soul (spirit) ever possess a bodily (or even body-like) trait, and if so which one(s)?

Name your sources, if you like, but PLEASE do NOT reproduce the entire content of any “holy” book here to make/support your case – I’ll take your word for it. :-) … I am, in fact, only interested in the underlying spirito-physiological mechanisms of soul-separation and nature, IF ANY, as opposed to the theological proof (or NOT) of its existence. Again, I am interested in YOUR understandings and interpretations of the issue at hand (based on your intuitions and/or faithful references) and not verbatim reproductions of chapters and verses of “holy” books of faith. Please be concise and, above all, TO THE POINT. …Thank You!
