In the soliloquy in act2 scene1 Macbeth creates an image of a dagger just floating in front of him. ‘Is this a dagger which I see before me’ At first you would think that the witches created this image for him however, based on past events of Macbeth always questioning himself, we then realise that he was hallusinating. He starts to regret his decisions. ‘A dagger of the mind, a false creation’
