In the start of the scene, everything that is happening seems to not be normal, all of things that were happening indicates how dark is the plan of killing Duncan. Banquo had a bad dream, which made him remember to give Lady Macbeth the diamond that the King brought especially for her. Which shows how bad Lady Macbeth and Macbeth’s plans are. Macbeth then tells the servant to go to sleep to than Macbeth imagines a dagger with handle pointing toward him, full of blood. Macbeth the has a soliloquy (a soliloquy is when a person talks to himself trying to persuade himself of doing something) that ended with him thinking that it is a sign to conform the killing of Duncan. I think that Macbeth is acting against god’s will, and that he is disturbing the natural order.
MACBETH
(to the SERVANT) Go bid thy mistress, when my drink is ready,She strike upon the bell. Get thee to bed.Exit SERVANT
Is this a dagger which I see before me,The handle toward my hand? Come, let me clutch thee.I have thee not, and yet I see thee still.Art thou not, fatal vision, sensibleTo feeling as to sight? Or art thou butA dagger of the mind, a false creation,Proceeding from the heat-oppressèd brain?I see thee yet, in form as palpableAs this which now I draw.Thou marshall’st me the way that I was going,And such an instrument I was to use.Mine eyes are made the fools o’ th’ other senses,Or else worth all the rest. I see thee still,And on thy blade and dudgeon gouts of blood,Which was not so before. There’s no such thing.It is the bloody business which informsThus to mine eyes. Now o’er the one half-worldNature seems dead, and wicked dreams abuseThe curtained sleep. Witchcraft celebratesPale Hecate’s offerings, and withered murder,Alarumed by his sentinel, the wolf,Whose howl’s his watch, thus with his stealthy pace,With Tarquin’s ravishing strides, towards his designMoves like a ghost. Thou sure and firm-set earth,Hear not my steps, which way they walk, for fearThy very stones prate of my whereabout,And take the present horror from the time,Which now suits with it. Whiles I threat, he lives.Words to the heat of deeds too cold breath gives.

You’ve done well at interpreting much of what happened. I think you may have misunderstood the ‘diamonds’ part – who is it that gave those to Lady Macbeth?
