Question

How does macbeth feel after he sees the first 3 apparitions in scene one

Answer 1

The first is an armed head, summoned to warn Macbeth that Macduff is coming back to Scotland to ruin him. The second apparition is a bloody child and it tells Macbeth that no man born of a woman can do him harm. This gives Macbeth great confidence: "Then live Macduff: what need I fear of thee?" (4.1.78-80). The third apparition is that of a child wearing a crown and holding a tree. It declares: 

Macbeth shall never vanquish'd be until
Great Birnam wood to high Dunsinane hill
Shall come against him (4.1.87-90). 

Macbeth is sure that the third apparition's prophecy will never be, for 'who can impress the forest?' or 'bid the tree unfix his earth-bound roots?' (4.1.91-3).
