Has anyone got photos in their house that have others within them ??

I have a old shot of my great grandparents up looking at me and when my grandma (she was 98yrs) passed (their daughter) and year later Grandmas profile can be seen in the photo !

A psychic friend saw it when i showed her a photo i took and inadvertently the photo was in this photo and she said to me Your grandma is still with you ....and then when i looked i saw grandma in the photo with her parents....

In the same photo my g grandparents are sitting down and slowly but surely there is a third person (spirit) slowly coming out but wont show the head yet but i can see its a women sitting wearing the old dress with her hands either folded over each other or clasped together in front ... and there is a small girl next to g grandma and i can see her outline with long dark curls but again no face....

I have asked my dad if he knew if grandmas mum had stillborns or anything significant but Dad doesn't believe in all this so he shuts the conversation down !

Im not all scared im very flattered and to be honest feel very safe as i believe i have my grandma her parents with me all the time ....

How could i get the other 'faces' to show in the photo?
