A gal from our church related the story of when her husband died. Shortly before he died the ghost of his dead father showed up in the hospital room with the dieing man and his wife. He stayed for awhile and then left, leaving the wife in a comforted state. (Can’t recall if she said “he” spoke or anything.)
She was a bit in wonderment about what, or if, it had really happened. Until the nurse came back in and said something like “I came by earlier but didn’t want to disturb you when you had a visitor.”
I believe it to be true, but who knows.
If that did happen, God certainly allowed for it to occur.
I know a guy who has said that on more than one occasion he has seen the sould of people he was close to that had just died leaving through the hospital roofs up to heaven. On those occasions he had been on the way to the hospital to visit them and had seen a visual phenomena of a light orbish thing that made its way through the roof and went up into the night. (No not a helicopter, the hospital in question has no helipad or any air traffic around it.)
