True story. I was very young at the time but my mother was in the garden and looked back into the sitting room and saw her grand father sitting there, he had been dead for some time and had never been to that house. My mother loved him dearly as he had looked after the family after her father had died in WWI. My grandmother on my father’s side was also in the garden and as she was a bit nutty so my mother did not ask her if she saw my mothers grand father also, she would have said yes. So my mother said said what do you see in the sitting room and my grand mother, straight away said Good God it’s your grand father. He then disappeared, weird but gives you faith in the after life.
