Mysteries of my subconscious

So I was at a party of some sort, and everybody was having a good time, but me and a few other people could sense that something was going to go wrong. We were trying to kind of make sure everything was alright, but really weird thing were happening, like the pool would drain. Then more water would pour out of the back. and that happened two or three times. There was some hole in the ground that was man made, but I don't remember the justification for it. We made it for a reason, a long while before all this. But people were climbing down that, just to check it out, and some returned but others didn't. We tried to disallow people from going down there. Others were being killed in brutal ways. Eventually the water flooded the area and more people were being killed more easily. I tried to urge everyone to get out, and I did as well.
I got out really easily, and there was an out of control car/boat thing on this lake nearby. I jumped on that to see if anybody was alive on it, but it was empty. There was also a giant ship that was empty, but still going at high speeds on the water.
I was at that point trying to get to the shore. I got on the car boat thing that was farther inland than the boat, and tried to abruptly turn, and the waves slowly turned the large boat too. It turned easily as if some force was trying to kill me with it. But I managed to get around it, and made it to land.
I was just trying to rush to somewhere safe, which turned out to be some music lounge, and there was a private room and I sat in there. I tried everything I could to see if my girlfriend was okay, but I couldn't find anything. And then I woke up.
