Not totally my story, and I don't believe in any of this shit so whatever just contributing
Anyway:
My Cousin recently died, he was 20 something, so my aunt and uncle were destroyed about it. He was actually murdered by his then girlfriend with a rock in the woods, which is a story for another time. For about 3 straight months after he died, ever photo the aunt or uncle snapped would have a silhouette of a white hand with 4 fingers. The significance of this is that my cousin was born with a rare birth defect where he had four fingers on one hand and 6 on the other. My aunt is convinced he is telling her he is ok and is moving on, but I don't know, I'm a skeptic.
It's a REALLY touchy subject, so if I can get pics of the photos I'll send them to you, but I'd honestly rather not bring it up with my aunt.
