For, as I have shown before in the second chapter, dreams be naturally but the fancies remaining in sleep, after the impressions our senses had formerly received waking; and when men are by any accident unassured they have slept, seem to be real visions; and therefore he that presumes to break the law upon his own or another’s dream, or pretended vision, or upon other fancy of the power of invisible spirits, than is permitted by the commonwealth, leaveth the law of Nature, which is a certain offence, and followeth the imagery of his own or another private man’s brain, which he can never know whether it signifieth anything or nothing, nor whether he that tells his dream say true or lie; which if every private man should have leave to do, as they must by the law of Nature, if anyone have it, there could no law be made to hold, and so all commonwealth would be dissolved.
