Weird dream, please interpret?

I had this dream in which I was in a lake and there was a this theme park attraction (I dont remember the name you know the one thats like wheel) and my high school clmates were on it (im in college now) and then this man came and let free 2 crocodiles and told me to run because we was going to let them free so I ran and then woke up scared. What does this mean?
