Read the following extract in which Macbeth has seen a vision of a bloody dagger and his head becomes filled with disturbing images. Then answer the questions which follow.
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 half-world
Nature seems dead, and wicked dreams abuse
The curtained sleep. Witchcraft celebrates
Pale Hecate's off'rings, and withered murder,
Alarumed 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.
(Act 2 Scene 1)
