Really interesting stories. I think there isn't a soul living inside of a living being that will transfer from one life to another after the death. Even though I don't think there isn't a something called as a soul, I do think there are ghosts and that kind of supernatural stuff. In the philosophy I'm believing in, it is said that living beings will reborn after their death, and for a human being, it is a worst living form such as ghosts which is a less severe form of the four worst living forms that humans will gain most of the time after their death. 

As I think, what happened after a death is not like that a soul of a living being is getting transfered to anthor living form, but it is something like fruiting a nut from a flower in a tree. So it cannot be said as the same soul or something like that is living in the second outcome. It cannot be said it is the same living being or it is a different living being. It is the result of its previous state.

I haven't seen any ghosts, but I have experienced quite unbelievable incidents that odds of them to be happened are like one to million, or there are no odds at all that I can think of.  Universe is full of various stuff that are beyond our human mind. So I think we can't be judgemental on anything; we are better to be open-minded.
