How intelligences are given or received, we do not know; nor are we sensible how they are conveyed from spirits embodied to ours that are in life; or, on the contrary, from us to them; the latter is certainly done without help of the organs, and the former is conveyed by the understanding, and the retired faculties of the soul.
The spirits, without the help of voices, converse, and the more particular discoveries of converse of the spirits, seem to me as follow: to wit, dreams, voices, noises, impulses, hints, apprehensions, involuntary sadness, &c.
Dreams of old were the ways by which God himself was pleased to warn men what services to perform, and what to shun. Joseph was directed of God in a dream to go to Egypt; and so were the wise men warned in a dream to depart into their own country another way, to avoid the fury of Herod. I am not like those who think dreams are the mere designs of a delirious head, or the relics of a day's perplexities or pleasures; but, on the contrary, I must beg leave to say, I never met with any capital mischief in my life, but I had some notice of it by a dream; and had I not been a thoughtless unbelieving creature, I might have taken many a warning, and avoided many of the evils I afterwards fell into, merely by total neglect of those dreams.
I was once present at a dispute between a layman and a clergyman, upon the subject of dreams. The first thought no regard should be given unto them; that their communication from the invisible to the visible world was a mere chimera, without any solid foundation. For, first, said he, if dreams were from the agency of any prescient being, the motives would be more direct, and the discoveries more plain, and not by allegories and emblematic fancies, expressing things imperfect and obscure. 2. Since, with the notice of evil, there was not a power given to avoid it, it is not likely to proceed from a spirit, but merely fortuitious. 3. That the inconstancy of such notices, in cases equally important, proves they did not proceed from any such agent. 4. That as our most distinct dreams had nothing in them of any significancy, it would be irrational and vain to think that they came from heaven. And, 5. That as men were not always thus warned or supplied with notice of good or evil, so all men are not alike supplied with them; and what reason could we give, why one man or one woman should not have the same hints as another.
