Crow listens Sky's question and for once he could give her some solid answer;<strong>"Ghosts are easier to explain. When person dies, it splits up into two souls, higher soul and lower soul. Lower soul holds all our animal based instincts and emotions, while higher soul holds our emotions, thoughts and thinking in general.<br/><br/>Hungry ghosts are nothing but lingering lower souls which should disappear in time if they do not persist through very strong animal based emotion; which is hunger for blood, flesh or other such thing.<br/><br/>Higher souls usually pass on to lethe where they as person they literally vaporize and become one of a greater whole in nirvana and bliss. Then from <em>Lethe</em> a portion of it's energy is send back to Creation to newborn child. Now some people may tell they get feelings or emotions which may be from past life so notion about reincarnation is not far fetched. But even then if there is some echo or recycle in essence pattern in soul, the said soul is brand new person which will be different from former incarnation if some things are similar.<br/><br/>Now, normal ghosts are simply souls, higher souls which simply <em>refuse</em> entering Lethe. Now this cannot be just by will alone, as central identity of each ghost is their <em>passion</em>. A strong emotion which they experienced during their final breath, a emotion which made them scream 'I must stay for this!'. Examples of said emotions can be revenge on killers, compassion for spouse who will be all alone while your gone, or you had a strong determination to achieve your goal and your determination carries to refuse lethe until task is done. Or negative emotions like killer wanting one last thrilling murder to do before he passes on."</strong>
