Komentarz do Hioba 33:16

Then He opens the ear of men as He did to Abimelech in the dream of the night.

Malbim gives the following explanation of how these dreams work:
It is the moral force implanted in man's soul that gives him his sense of right and wrong. And it is by virtue of this force that he is roused to be moved by the dream and to examine his deeds. For the moral sensibility embedded in his [divine] soul prophesies to him, through the impact of the dream, that he has exceeded the bounds of morality. Thus it appears as though the dream inscribes these things on his soul. And in order that he believe that the message was from God, the moral force in his soul puts its signature to it, authorizing and confirming the truth of the message, so that he should feel, by the nature of his soul, that he has sinned and been warned from above.
The moral force in his soul first makes man take note of the dream and then confirms its truth. The overall result is that his conscience has been pricked.

and with their chastisement He seals [them] He seals them and binds them with suffering because of their iniquity.
