This is my mum's story, but she doesn't mind me putting it up.
I can't remember the exact date of the sighting but I know it was AFTER the death of Princess Diana. It was within the week that her funeral took place.
My mum claimed she was sat in our living room watching the T.V when something caught her eye in the garden. Our T.V back then was in the corner of the room and the front window was to the side of the T.V, so you could see straight out into our garden and the road.
She said she saw a grey coloured head, of what looked like a middle aged man with a woman's short hair style, floating above the grass. At first she though it was a reflection from the T.V or something but the head continued to hover in the air outside for a few minutes before vanishing.
She told a few people that day including me, my dad and one of my sisters what she had seen. My dads not really a big believer of ghosts/spirits so he shrugged it off as a reflection off the T.V. Me and my mum however have always said that we don't need telling there is an afterlife because we already know there is one, we also have our own theories for Deja Vu's etc.
Anyway, the next morning she had woken up and had began reading the paper, most pages were dedicated to Princess Diana's death, only to turn the page and see a picture that caught her eye and made her a bit freaked out. Someone had carved a life sized Bust of Princess Diana's head out of grey coloured rock. However the face resembled that of a middle aged man, not Diana. She showed us the image in the paper and claimed this is what she saw floating in the garden.
To this day she still has the paper in the loft in her house.
Comments welcome, thanks for reading!
