Macbeth is feeling invincible in this scene. His mania has risen to a level where he feels he cannot be touched or hurt until Birnam wood comes to his castle, which he believes to be an impossibility. He has taken the witches' prophecies and held them in his mind as if they put him on top of the world. He carelessly yells at his staff and demands that the doctor just simply fix Lady Macbeth.
