What is this dream saying to me?

My dream is like a really bad monster flick. I'm one of the people that are running about being chased by this enormous monster crocodile that I have seen come out of quicksand and just chases after me. I'm also trying to help my friends out. I lost one of them. But the others survived. When I was helping out a girl who is my friend out the croc was coming for us and just as he was getting jump on me, I woke up! What does this mean?
