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?
