As kids we used the phrase all the time to describe when one got a shiver up the spine due to the creepiness of something
But it wasn't until my mid-twenties that I realised what I was saying. It was just what you said when it happened, a ritual call, chant, a hex or something - I only ever noticed the rhythm of the phrase as a kid, not the actual meaning.

But on thinking about it, it's perhaps one of the darkest things a kid could say:

"Someone just walked over my grave."

I always took it to mean:
"Someone just walked over the place where I'll one day be buried", which always raised more questions for me than it answered, like, who are all these people who are wandering around graveyards and stepping on the unused plots? What if I drown at sea? Does it happen if an ocean liner passes over my final resting place? How about all the people who are cremated? Is someone walking on the mantelpiece in what will one day be their nearest and dearest's home? Or walking on the tiger that will one day eat you?

But the Algarve is such a nice place, so many tourists, it's bound to happen sooner or later, right, Maddy? Now, have this special drink and settle down, Mummy and Daddy need to go and eat Tapas in peace...

But it makes no sense.
Unless you're already dead and a ghost, in which case the bad part, dying, has already happened.

Unless of course
Spirits are not bound by the earthly laws of time and space.

So, someone in your subjective future walked over your grave.

Or, maybe walked wanked
