Dream of church

At first, a group of boys, from a church, apparently. They were searching something, me included. Behinf us, there was a forest, just as ahead. We were on a roughly rectangular clair. We tried to enter the forest ahead, which was full of thin trees. There was a nun, our caretaker. She was near a...tree. It was light colored and full of sections of "spikes", long and tbular, with flat tips. "You are the Lord's spikes" She said. We got really annoyed, since we were busy. There was a fight. One group wanted to explore south, and other one, north, I was on the side wanting to go north, since I had a map and that is where it pointed. They went south anyways. Weirdly, the map showed they walking. They arrived at the place I knew it was a beach, even if it wasn't shown on the map. There were names of unknown, dangerous islands on it, We called for them. After that, I was alone in the dream, going north. There were no longer forests, but plains with light green grass, with trees growing here and there. I found a full armor set, red, made out of copper, with protusions on some places. It was forgotten for the rest of the dream. I found a dog, tiny and brown, pretty much like my real life dog. There was a guillotine. Big, dangerous. Near it, a chest. A little further away, another one. I noticed that going near a chest made my dog go near the guillotine, so I deduced it was a trap. I went away, pondering whether I should try the further away chest, probably not connected to the trap. I pressed "E" to open the inventory. When I closed it, the dog had been beheaded and the chests were now signs with the reading: "Life is ------" I don't remember the last word. There was a beach. Not shown in the map, either, but beautiful. White sand near the short grass. This is where the dream ends, near the beach with unknown islands on the map.
