What metaphors are used in Macbeth by William Shakespeare?

Most of the play is rich with metaphors:

Doubtful it stood;
As two spent swimmers, that do cling together
And choke their art. Act 1 sc 2

The Thane of Cawdor lives. Why do you dress me
In borrow'd robes? act 1 sc 3

There the grown serpent lies; the worm that's fled. act 3 sc 4
