Wow..I would have been scared as well.
Its sad to wonder who she was & what had happened to her & why she needs help to get to heaven..like maybe she was murdered or injured & her body never found? Could it be an unsolved mystery & her body is near where you saw her?Maybe she cannot rest & go to the light until she is found? How old did she appear & from her clothing..can you determine what era she was from? Can you somehow look up and see if there were any disappearences from that time?
I do beleive as I have seen a ghost before but I wasnt scared because it was my dog. (I will post that & other stories soon). Seeing is beleiving.
