Retribution, maybe. It is Macduff who is knocking. Conscience, possibly. Lady Macbeth says, "Hark, more knocking! Get on your nightgown lest occasion call us and show us to be watchers" Damnation, perhaps. That is the essence of what the Porter says: that the knocking is someone trying to get into Hell.
Macbeth wishes the knocking at the gate could wake Duncan from his sleep after he murders him, so he could continue to act innocent.
On the Knocking at the Gate in Macbeth was created in 1823.
In the sleepwalking scene (Act V Scene 1) she goes back to bed when she dreams or imagines that she hears knocking at the gate. "To bed; to bed. There's knocking at the gate. Come, come, come, come, give me your hand. What's done cannot be undone. To be, to bed, to bed."
In Act 2 of Macbeth, King Duncan is murdered by Macbeth in his sleep. Lady Macbeth also kills the two sleeping guards to frame them for the murder.
It was Macduff who was knocking on the door after Macbeth killed King Duncan.
Lady Macbeth totally sucks Macbeth's dick right now.
In Act 2 Scene 1, Macbeth is onstage and Lady Macbeth is not. I think Macbeth in Act 1 Scene 5 is heading back to his castle called "Inverness" to talk to his wife (Lady Macbeth) about what happened with the witches and to come back from the war that just happened. Possibly you were thinking of Act 2 Scene 2 where she is talking and he is stabbing Duncan.
In Macbeth's soliloquy in act 2 scene 1, Macbeth imagines that a dagger is leading him to the place where he is to kill King Duncan. This is an example of the power of Macbeth's imagination and how easily it can take over.
Macduff refuses to attend Macbeth's coronation.

In Act 2, Scene 1 of Macbeth, the king, Duncan, is in a pleasant and gracious mood. He comments on the beauty of Macbeth's castle and expresses gratitude towards Lady Macbeth for hosting him.
It depends what part of the play you are talking about. Macbeth is a wonderful play because the main characters do not have a fixed character profile. What they do in Act 2 changes them forever. Killing someone while they sleep was out of character for Macbeth in Act 2 but would not be in Act 4.
