FLOATING IN THE MIDDLE OF THE OCEAN THEN INTO A DUNGEON

in this one i was for some reason in the middle of the ocean and i was floating face down. I should have became lucid because, I was facing down in the water and i could still breath i even noticed it. But anyway it was other people out there with me the thing i noticed was, that some of them were walking on the water. Then out of nowhere like a big ship comes by and people start to get on it. Then the scene changes and i am in a dungeon remember throwing up in the dream or trying to. It was feces in my mouth, i couldn't taste it but i knew what it was. While i was down there somebody said something about a bible .I noticed that the people there with me ,were people that i knew but they really weren't my friends .Nobody was in chains or anything but it was all brick and dark in the dudgeons what does it mean to be in a dungeon.
