Wow, I find this frightfully interesting! Though I, too, think this is not how things should be!
Way back in 1985, I came across a similar sight on a cemetary in South Spain which was in the process of being moved from its old plot to a new one on the fringes of the community. Or so it was said. I never saw any "moving" activities going on while I was in the area, but what do I know?
What I did SEE, though, was an open grave like this, though a "wall grave" the one in Spain was, if you know what I mean: not one down in the ground but in a deep wall (sort of like a "block of grave-flats").
Well, it so happened I went to and entered (listen carefully now!) this cemetary in the middle of the night one night! I wanted to see a sky with so many stars like I had never seen before, and this cemetary happened to be the darkest place in the entire community. So there I wanted to be and watch the stars, and the sight I was having down towards the sea and the town and its lights.
When I carefully inched nearer to where I knew the open grave was, I suddenly saw something that seemed not from this world!
The skeleton sent out the faintest, but still distinguishable (!) glow of fluorescent light. Really, really, REALLY faint, but the light was there. Honestly. I'm not kidding!
