Scene (i) starts with the witches, who are standing in a circle around their cauldron, throwing things in, like the tongue of a dog. Then suddenly Macbeth arrives and asks them to tell him some more prophecies. As the first prophecy they tell him to be careful of Macduff, Thane of Fife. As the second prophecy they say he can't be killed by anyone who was born of a woman and as the third prophecy the witches say if Birnam Wood stays at its current position Macbeth is okay but if the wood moves he will have problems. Macbeth is happy because he thinks that all of these things are impossible. He wants to know a fourth thing but suddenly the witches dance crazily and then run away.
