I’ve been working on an essay for a couple of days now, I want to explain how Macbeth becomes more delusional and paranoid in Act III. I’ve found a few quotations but I am not quite sure about their meaning:

1) “It will have blood, they say; blood will have blood. Stones have been known to move, and trees to speak; Augurs and understood relations have by maggot pies and coughs and rocks brought forth the secret’st man of blood” (3.4.151-156)

2) “I am in blood stepped in so far that, should I wade no more, returning were as tedious as go o’er. Strange things I have in head, that will to hand, which must be acted ere they may be scanned” (3.4.167-172).

3) “My strange and self abuse is the intiate fear that wants hard use. We are yet but young in deed.” (3.4.174-176).

Thank you very much,
