One servant did laugh in 's sleep and one cried. "Murder!"
A foolish thought, to say a sorry sight.
Macbeth kills the king in his sleep, and feeling stressed about what he did, goes to talk with his wife to tell her about the weird noises that he heard of the servants.
Macbeth enters, holding a bloody dagger, asking his wife if she heard the noises. Lady Macbeth is surprised by seeing him and tells him that she heard the owl scream and the crickets cry.
Macbeth, looking at his hands covered in blood, says it is a sorry sight meaning that the sight is painful and upsetting. He also mentions to Lady Macbeth some of the voices that he heard while he stood and listened. He said that the servants just said their prayers and fell back asleep.
