I hope that helps. Good luck
The supernatural plays a large role in Macbeth. Had the witches not talked to Macbeth in the beginning of the play & told him of what he could become, none of the events that followed would have taken place. This gives an overall dark mood to the story. The mood relates to the play's central conflicts because after talking to some really dark and evil beings, Macbeth does some dark and evil things.
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
<span>Shall come against him (4.1.87-90). </span>
<span>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). </span>
