rock" In this quoet, macbeth is comparing his prior state of existing to a marble rock, saying that he was person who used to be strong and in a solid position but now that has all changed due to his doubts and fears.

rock". Macbeth used this imagery when talking about his state of mind and when the murderers were telling him that Banquo was killed.

rock". In this quote, Shakespeare uses tactile imagery to make the audience feel how Macbeth would have felt had the murderers killed both Banquo and Fleance. When used in the test it is meant to kind of exaggerate his paranoia, but it shows how he is so worried as to use this simile to describe his would-be state of mind.
3)  "I am cabined, cribbed, confined, bound in To saucy doubts and fears". This example of imagery is to visually represent how Macbeth feels hopeless due to the failure of the murderers. Confined in this sense means trapped in paranoia because he believes that Banquo's son will be king, which likely means he must take the crown by force from what Macbeth has done, and Macbeth wants him gone to avoid that happening.

rock".  Here we can see Macbeth paranoia developing as Fleance escape. This shows Macbeth insecurity of his position as a king and how anxious he is that Fleance can become the next king.

"I am cabined, cribbed, confined, bound in To saucy doubts and fears". This imagery shows how big Macbeth fear are now that the two man failed to kill both Banquo and Fleance. He is now trapped in his own fear and paranoia.

The guard assures Macbeth on Banquo’s death by visually describing the situation of his death. One may visualise the cruel death Banquo had to go through as a result of Macbeth’s paranoia and greed of power. The word "safe" emphasises on how Banquo is better off dead since Macbeth lacks the nature of a true king. 

“He’s lying dead in a ditch, with 20 deep gashes in his head.” This line is a combination of visual and tactile imagery. Firstly, we can imagine how Banquo would look coming back from the dead, how there would be blood on his head, etc. Tactile imagery is also used because they hint that there are TWENTY gashes on his head, and obviously the audience would imagine his pain. 

“A bold one, that dare look on that which might appeal the devil.” He says that he is a valiant and brave man, which takes a gander at something that may startle the devil. this specific line tells us that the action that the nurseries have done would intimidate the devil, which is the head of evil and slaughter, therefor indicating the heaviness of his action. 

"But now I am cabined, cribbed, confined, bound in To saucy doubts and fears.-But Banquo's safe?" In this quote, Macbeth utilizes irony. His used this by depicting Banquo's state when he inquired as to whether Banquo is protected. However this is ironic because he is dead, however Macbeth is so suspicious and paranoid that he implies is he protected from Banquo. Furthermore, he asks this through his failure, he is so jumpy of Banquo uncovering him.

"There the grown serpent lies; the worm that's fled hath nature that in time will venom breed, no teeth for th'present." In this statement, Macbeth is saying that assuming Fleance is as yet alive, he can be hurtful to him later on by beginning a revolt by understanding what Macbeth has done. This clearly means that Macbeth perceives that despite the fact that Fleance has no force at this moment, he has the ability of force sooner rather than later, is as yet a danger.

As we can hear Macbeths thoughts, and we also know that Banquo and king Duncan were murdered
