Interesting story.
I am not really a religious person, but I have an idea that people DO come back in a manner of speaking.
I once had a very strong feeling that I needed to leave the house, get in my car and go to my deceased friends' house. It was important to visit her widower and her children. I fought it off for a while, but finally it was too strong and I did that. Drove to her house and knocked.
As soon as the door was opened by her son, the impelling feeling that I needed to visit left, and I felt a sigh of relief all around me. The kids seemed happy to see me and her husband who was suffering from a devastating head injury, seemed happy too.
the kids opened up to me about their Dad, and their frustration with how he was not doing so well mentally.
That day, he asked me to become their Godmother in case something happened to him.
While I was in the house, I could feel her presence. It was very odd and very overpowering. The kids felt it too, they told me.
Just before she died (cancer) she asked me to keep an eye on them, and of course, I said I would. but after his accident I had stayed away to give them space and privacy.
Was it a paranormal manifestation? I don't know, but how come that insistant feeling that I needed to go to the house? How come that feeling that she was in the room with us, watching lovingly.
