“A citizen who is waked by one of these criers, may regard him as a kind of remembrancer, come to admonish him that it is time to return to the circumstances he had overlooked all the night time; to leave off fancying what he is not, and prepare to act suitably to the condition he is really placed in.”
That may be called a dream which proceeds either from the spirit of the phantasy and intellect united together, or by the illustration of the agent intellect above our souls, or by the true revelation of some divine power in a quiet and purified mind; for by this our soul receives true oracles, and abundantly yields prophecies to us; as in dreams we seem both to ask questions and learn to find them out. Also many doubtful things, many policies, many things unknown, unwished for, and never attempted by our minds, are manifested to us in dreams; also the representation of things unknown and unknown places appear to us, and the images of men, both alive and dead; and things to come are foretold, and also which at any time have happened are revealed, which we know not by any report. And these kind of dreams need not any interpretation, as those which belong to divination, not to foreknowledge; and it comes to pass that they who have dreams for the most part understand them not; for, as to have dreams is from the strength of imagination, so to understand them is from the strength of understanding. He, therefore, whose intellect being overwhelmed by too much commerce of the flesh, is in a deep sleep, or his fantastic power or spirit is too dull and unpolished, so that it cannot receive the species and representation which flow from the superior intellect; this man is altogether unfit for the receiving of dreams and prophesying by them. Therefore it is necessary that he who would receive true dreams, should keep a pure, undisturbed and imaginative spirit; and so compass it that it may be made worthy of the knowledge and government by the mind, for such a spirit is most fit for prophesying and is a most clear glass of all images which flow everywhere from all things. When, therefore, we are sound in body, not disturbed in mind, our intellect not made dull by heavy meats and strong drink, not sad through poverty, nor provoked through lust, nor incited by any vice, nor stirred up by wrath or anger, not being irreligiously and profanely inclined, not given to levity, nor lost in drunkenness; but chastely going to bed, fall asleep, then our pure and divine soul being free from all the evils above recited, and separated from all hurtful thoughts, and now freed, by dreaming, is endowed with this divine spirit as an instrument, and receives those beams and representations which are darted down as it were, and shine forth from the divine mind into itself, in a deifying glass. It does more certainly, more clearly and efficaciously, behold all things, than by the vulgar inquiry of the intellect and by the discourse of reason. The divine person instructing the soul, being invited to their society by the opportunity of the nocturnal solitariness, neither will that spirit of genius be wanting to him when he is awake, which rules all our actions. But there are four kinds of true dreams, viz.: the first, matutine, _i. e._ between sleeping and waking; the second, that which one sees concerning another; the third, that whose interpretation is shown to the same dreamer in the nocturnal vision; and, lastly, that which is related to the same dreamer in the nocturnal vision. But natural things and their own co-mixtures likewise belong unto wise men, and we often use such to receive oracles from a spirit by a dream, which are either by perfumes, unctions, meats, drinks, rings, seals, &c. Now those who are desirous to receive oracles in or through a dream, let them make themselves a ring of the sun or Saturn for this purpose. There are likewise images of dreams, which being put under the head when one goes to sleep, effectually give true dreams of whatever the mind hath before determined, of which as follows:
