Is this a dagger which I see before me, 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

Summary

This quote is from Shakespeare's play Macbeth, spoken by the character Macbeth as he hallucinates a dagger before committing a murderous act. Macbeth questions whether the dagger is real or a figment of his imagination. He wonders if it is an external object that he can physically grasp or simply a reflection of his troubled mind. It reflects his unstable mental state and inner turmoil as he contemplates the consequences of his impending actions.
