He impatiently asks about them and any truth to their prophecies. They summon the first ghostlike figure who warns Macbeth of Macduff and then descends. It confirms Macbeth’s fear. The second apparition rises which is a bloody child who says that none of woman born will ever harm Macbeth.
The third apparition is a crowned child with a tree in his hand. It assures Macbeth of his invincibility until Birnam Wood starts moving towards Dunsinane Hill. These three apparitions falsely lessen the deep fears of Macbeth.
