"'[F]ear can't hurt you any more than a dream. There aren't any beasts to be afraid of on this island....Serve you right if something did get you, you useless lot of cry-babies!"
(P) predict. The writer of the following quote is saying that whomever they are adressing, they need not be afraid anymore, for they are in a dream, and the beasts aren't worth their fear. "Serve you right if something did get you, you useless lot of cry-babies!" means that the writer thinks that whomever they are adressing should have had something done to them, if they can't seem to stop being afraid.
