Crossing The Lake at Midnight

There is a large, lake that I have to cross for some reason. It is midnight and hence, very dark outside. It's pitch black. It is kind of scary for some reason. There is some type of high school activity going on in a lit up warehouse type place. It is either a football game after party or school dance. It's like a pole barn with a huge light outside. I'm wandering around outside. I walk past several teenagers and then decide it's time to cross the lake. I start swimming and suddenly someone I know is swimming across with me. I see a dolphin swimming up next to us. It's really exciting until I become afraid. I have a terrifying feeling the dolphin will turn into a shark and attack us. I feel like I have seen that in a movie or on the discovery channel. I try my best to block it out and we eventually make it to the other side. I climb up a dark brown ladder up to a dock. I see a large group of homeless children shivering and huddling together in a corner of the fence. I instantly run over and scoop of the baby and let the small kids wrap their arms around me. For some reason, I am not wet here. I am warming them up because they are so cold. I don't know why all these kids have been abandoned but I am not letting them stay like this. I decide to sleep there with them and in the morning I will figure out what to do. I wake up.
