Huhwhatsthat

Me and my dad are on a large grassy and mountainous islands, when suddenly the tide starts rising. It doesn't rise continuously, but rises by a large increment every so often. Me and my dad climb and swim our way to higher ground, and as the water rises only 4 mountains that now look like islands remain, the only ones not fully submerged. From order of lowest to highest, I will assign them 3, 2, 1a and 1b. We swim across the water from the top of 3 to get to 2, and the water rises again as we arrive. My dad points out to me a dead fish in the water that I don't see, but I realize that all life underwater has somehow died. On 2, an older woman awaits and discusses which mountain we should swim to next (1a or 1b), and I know she won't be coming. The mountains are both in front of us, 1a is slightly lower than 1b and has a dirt path leading up to a dirt plateau. 1b is a large forest. I also notice a large ruined structure connecting the mountains, that looks like it could have been a ruined bridge from Fallout, and there is also a layer of stone and metal wire debris on top of the water directly underneath it. I have a feeling that we should go to 1a for some reason, but my dad and the woman decide on 1b because it's higher, and I agree. As we begin swimming, I see a dead see creature, and then my asshole friends wake me up by throwing pennies at me.
