What do these dreams mean?

I had this dream that I was with two (unknown, a man and woman) people and we were by a swamp. The swamp seemed to be full of blood with deformed, oversized and some normal looking alligators and snakes. But the two people ran in. The creatures were attacking them but they seemed to enjoy being attacked and they laughed. I remember seeing a gaping wound in the womans shoulder but she was smiling. I told them to get out because they were going to die. Thats when I woke up.
