I have a black stone with a mark on it, as if it were a door. Then, in the same room, on a different wall, I found another black stone with a rectangle on it, as if it were an entrance. There's also another stone nearby with handprints on it. Please help, what does this mean?

Unfortunately or thankfully depending upon the answer you want, they look like rocks, that's it. Doesn't look anything like a door at all. Can you show us the handprints?
