Well the title explains most of it. I was making the underwater quest when I was getting milk from the village. I saw a waterstream coming out of the hill that the village sits on, so I tried getting in. It was glitchy and I was stuck in water. When I tried moving it teleports me back to the same spot. So I tried relogging by typing /lobby. When I came back I respawned inside a block. I am currently looking at the block -776 36 -1880.
