• Is this a dagger which I see before me looser,
• The handle toward my hand? Come, let me clutch thee.
• I have thee not, and yet I see thee still.
• Art thou not, fatal vision, sensible
• To feeling as to sight? or art thou but
• A dagger of the mind, a false creation,
• Proceeding from the heat-oppressed brain?
• I see thee yet, in form as palpable
• As this which now I draw.
• Thou marshall'st me the way that I was going;
• And such an instrument I was to use.
• Mine eyes are made the fools o' the other senses,
• Or else worth all the rest; I see thee still,
• And on thy blade and dudgeon gouts of blood,
• Which was not so before. There's no such thing:
• It is the bloody business which informs
• Thus to mine eyes. Now o'er the one halfworld
• Nature seems dead, and wicked dreams abuse
• The curtain'd sleep; witchcraft celebrates
• Pale Hecate's offerings , and wither'd murder,
• Alarum'd by his sentinel, the wolf,
• Whose howl's his watch, thus with his stealthy pace.
• With Tarquin's ravishing strides, towards his design
• Moves like a ghost. Thou sure and firm-set earth,
• Hear not my steps, which way they walk, for fear
• Thy very stones prate of my whereabout,
• And take the present horror from the time,
• Which now suits with it. Whiles I threat, he lives:
• Words to the heat of deeds too cold breath gives.
• A bell rings
• I go, and it is done; the bell invites me.
• Hear it not, Duncan; for it is a knell
• That summons thee to heaven or to hell.
