Peace,
i heard a woman ranting once about how spirits or ghosts talk to her. she said that when someone dies...they have 3 earthly days to roam about before the "Light" comes for them. for 3 days they can do whatever they want...but the thing was if the didn't "go in the Light"...they missed it and they're stuck here on earth. until what?...i don't know. i can't remember what she said...but it had something to do with us as living beings. there was something we could do to help them.
sounded a lot like that movie "Ghost".
