"Why do you dress me in borrowed robes?" In this quote, Macbeth is asking a man Angus why he is being promoted to Thane of Cawdor, meaning why should he be placed in a position already taken by another. The previous Thane was sentenced to death. This quote relates to the theme of appearances, because a person can hide their identity behind a fake person. The 'borrow'd robes," are just a metaphor for a position Macbeth thought was already occupied.
This describes Macbeth in the play imagining a dagger in front of him that he goes to grab but nothing is there. This happens while he is sleeping. At that very moment Macbeth gets up to kill the king.
"The wine of life is drawn, and the mere lees / Is left this vault to brag of." The wine of life is a metaphor for blood. Macbeth could be relating wine and blood in the way that they are both powerful and could be the same color (red wine and red blood). However Macbeth expresses his guilt for killing Duncan.
