I agree this sort of things happen and can really freak you out.
My grandfather was the sort of guy who you’d always feel safe with. Tough as fuck with no fear. I felt like a mad **** getting picked for rep squads, nationals etc, bigger, faster & stronger than everyone but even in his 60’s he could beat me in a race and get me in a bear hug I couldn’t move from.
We walked his greyhounds across the cemetery a bit and I liked to go with him, just to hear his stories and to really just be around him. We walked past the nun section one day saw a nun standing near a grave. The greyhounds went absolutely ballistic. Picture your dog freaking out like it’s the scariest thing they have seen with their hairs standing up as they try to run backwards whimpering l. I remember the nun as clear as day, standing there with neutral face, not smiling but not upset, just praying.
My grandfather said, “Good evening sister” as the dogs went absolutely crazy. She disappeared. Totally without a trace. I don’t fear a thing and don’t know if I believe in ghosts but get goosebumps talking about this. My grandfather went white and very very quiet.
Whenever we went even a street away from the cemetery after that the dogs went absolutely crazy and dug their claws into the ground so they didn’t have to go back there
