after life

they stay here casue they lefft somthing behind.......thats why ghost's stay here on earth, they need somthing like goods.......

yes, but they have a choice IMO. they choose to this or to do that. instead of going to the light or going to the void, they choose to remain a lost soul roaming Earth.

"And he said unto them, I beheld Satan as lightning fall from heaven."

^^^Go into the light you fall from it. Heaven = the superphysical. Below heaven is earth. Earth = physical. You go from physical/superphysical to just physical. And that last state of physical is enter out to hell.

^^That only happens to astral projectors though. Whew! Lucky I'm not one of them or I'd be doomed as the devil they are.
