While Macbeth also appears to see ghosts as a result of killing his friend and the king, it is very probable that his visions are caused by his conscience, as he is unable to get over the fact that he murdered his best friend and the king. Lady Macbeth also yields to hallucinations: "Here's the smell of blood still: all the perfumes of Arabia will not sweeten this little hand" (Lady Macbeth, Act 5, Scene 1).
