Katnap, I was thinking along the lines of , what are they doing on a day to day basis , can they move around freely like you or I or are they stuck in a particular time frame say like the day they died, are they living in a sort of ground hog day situation. from what I can make out there are different sorts of spirits like you said eg. spirit guides or lost souls, do you think the spirit guide could have been a lost soul once apon a time? Do they evolve? As I sit here thousands of questions pop into my head so sorry if this is a little disjointed.
