Job 33:15

"During sleep, in the visions of the night. By ignorance, or at the time of tribulation. "When a terrible terror seizes the sleeping man on his bed," thinking himself safe.

In a dream, in a vision of the night, when sleep falleth upon men, and they sleep on their bed. What is meant by the word of God being made known to us in a dream, except that we do not learn the secret things of God, if we are kept awake by worldly desires? For in a dream the outward senses are at rest, and inward objects are discerned. If we wish then to contemplate things within, let us rest from outward engagements. The voice of God, in truth, is heard as if in dreams, when, with minds at ease, we rest from the bustle of this world, and the Divine precepts are pondered by us in the deep silence of the mind. For when the mind is at rest from outward employments, the weight of the Divine precepts is more fully discerned. It is then that the mind penetrates, in a more lively manner, the words of God, when it refuses to admit within the tumult of worldly cares. But a man is awake to little good purpose, when the turmoil of worldly business gives him unusual disturbance. For the crowd of earthly thoughts, when it clamours around, closes the ear of the mind. And the voice of the presiding judge is less plainly heard in the secret tribunal of the mind, the less the sound of tumultuous cares is kept still. For a man when distracted is not fully equal to attend to both together. But while he seeks for inward instruction, but so as yet to be engaged in outward employments; by opening his ear to things without, he becomes deaf within. Moses, when living amongst the Egyptians, was, as it were, awake, and so when dwelling in Egypt he did not hear the voice of God. But after that he had fled into the desert, after the slaughter of the Egyptian, and dwelt there forty years, he fell asleep as it were from the disquieting tumults of worldly desires; and therefore it was vouchsafed him to hear the voice of God, because the more indifferent he became through Divine grace to outward objects of desire, the more was he really awake to discern truths within. And again, when appointed to rule over the people of Israel, he is taken up into the Mount, to learn the precepts of the Law, and is preserved from tumults without, that he might penetrate into mysteries within. And hence is it that holy men, who are obliged by the necessity of their employments to engage in outward pursuits, are ever studiously betaking themselves to the secrets of their hearts; and there do they ascend…
