The phenomena of dreams, of the exercises and convictions which occupy the mind, while the avenues of the senses are closed, and the soul is more or less extricated from its connection with the body, particularly in the peculiar conditions of partial slumber, are among the deep mysteries of human experience. The writers on mental philosophy have not given them the attention they deserve.

The testimony in these trials is particularly valuable as showing the power of the imagination to completely deceive and utterly falsify the senses of sober persons, when wide awake and in broad daylight. The following deposition was given in Court under oath. The parties testifying were of unquestionable respectability. The man was probably a brother of James Bayley, the first minister of the Salem Village parish.

"The Deposition of Joseph Bayley, aged forty-four years.—Testifieth and saith, that, on the twenty-fifth day of May last, myself and my wife being bound to Boston, on the road, when I came in sight of the house where John Procter did live, there was a very hard blow struck on my breast, which caused great pain in my stomach and amazement in my head, but did see no person near me, only my wife behind me on the same horse; and, when I came against said Procter's house, according to my understanding, I did see John Procter and his wife at said house. Procter himself looked out of the window, and his wife did stand just without the door. I told my wife of it; and she did look that way, and could see nothing but a little maid at the door. Afterwards, about half a mile from the aforesaid house, I was taken speechless for some short time. My wife did ask me several questions, and desired me, that, if I could not speak, I should hold up my hand; which I did, and immediately I could speak as well as ever. And, when we came to the way where Salem road cometh into Ipswich road, there I received another blow on my breast, which caused so much pain that I could not sit on my horse. And, when I did alight off my horse, to my understanding, I saw a woman coming towards us about sixteen or twenty pole from us, but did not know who it was: my wife could not see her. When I did get up on my horse again, to my understanding, there stood a cow where I saw the woman. After that, we went to Boston without any further molestation; but, after I came home again to Newbury, I was pinched and nipped by something invisible for some time: but now, through God's goodness to me, I am well again.—Jurat in curia by both persons."

Bayley and his wife were going to Boston on election week. It was a good two days' journey from Newbury, as the roads then were, and riding as they did. According to the custom of the times, she was mounted on a pillion behind him. They had probably passed the night at the house of Sergeant Thomas Putnam, with whom he was connected by marriage. It was at the height of the witchcraft delirium. Thomas Putnam's house was the very focus of it. There they had listened to highly wrought accounts of its wonders and terrors, had witnessed the amazing phenomena exhibited by Ann Putnam and Mercy Lewis, and their minds been filled with images of spectres of living witches, and ghosts of the dead. They had seen with their own eyes the tortures of the girls under cruel diabolical influence, of which they had heard so much, and realized the dread outbreak of Satan and his agents upon the lives and souls of men.

They started the next morning on their way through the gloomy woods and over the solitary road. It was known that they were to pass the house of John Procter, believed to be a chief resort of devilish spirits. Oppressed with terror and awe, Bayley was on the watch, his heart in his mouth. The moment he came in sight, his nervous agitation reached its climax; and he experienced the shock he describes. When he came opposite to the house, to his horror there was Procter looking at him from the window, and Procter's wife standing outside of the door. He knew, that, in their proper persons and natural bodies, they were, at that moment, both of them, and had been, for six weeks, in irons, in one of the cells of the jail at Boston. Bayley's wife, from her position on the pillion behind him, had her face directed to the other side of the road. He told her what he saw. She looked round to the house, and could see nothing but a little maid at the door. After one or two more fits of fright, he reached the Lynn road, had escaped from the infernal terrors of the infected region, and his senses resumed their natural functions. It was several days before his nervous agitations ceased. Altogether, this is a remarkable case of hallucination: showing that the wildest fancies brought before the mind in dreams may be paralleled in waking hours; and that mental excitement may, even then, close the avenues of the senses, exclude the perception of reality, and substitute unsubstantial visions in the place of actual and natural objects.

There may be an interest in some minds to know who the "little maid at the door" was. The elder children of John Procter were either married off, or lived on his farm at Ipswich, with the exception of Benjamin, his oldest son, who remained with his father on the Salem farm. Benjamin had been imprisoned two days before Bayley passed the house. Four days before, Sarah, sixteen years of age, had also been arrested, and committed to jail. This left only William, eighteen years of age, who, three days after, was himself put into prison; Samuel, seven; Abigail, between three and four years of age; and one still younger. No female of the family was then at the house older than Abigail. This poor deserted child was "the little maid." Curiosity to see the passing strangers, or possibly the hope that they might be her father and mother, or her brother and sister, brought her to the door.

In the terrible consequences that resulted from the mischievous, and perhaps at the outset merely sportive, proceedings of the children in Mr. Parris's family, we have a striking illustration of the principle, that no one can foretell, with respect either to himself or others, the extent of the suffering and injury that may be occasioned by the least departure from truth, or from the practice of deception. In the horrible succession of crimes through which those young persons were led to pass, in the depth of depravity to which they were thrown, we discern the fate that endangers all who enter upon a career of wickedness.

No one can have an adequate knowledge of the human mind, who has not contemplated its developments in scenes like those that have now been related. It may be said of the frame of our spiritual, even with more emphasis than of our corporeal nature, that we are fearfully and wonderfully made. In the maturity of his bodily and mental organization, health gliding through his veins, strength and symmetry clothing his form, intelligence beaming from his countenance, and immortality stamped on his brow, man is indeed the noblest work of God. In the degradation and corruption to which he can descend, he is the most odious and loathsome object in the creation. The human mind, when all its faculties are fully developed and in proper proportions, reason seated on its rightful throne and shedding abroad its light, memory embracing the past, hope smiling upon the future, faith leaning on Heaven, and the affections diffusing through all their gentle warmth, is worthy of its source, deserves its original title of "image of God," and is greater and better than the whole material universe. It is nobler than all the works of God; for it is an emanation, a part of God himself, "a ray from the fountain of light." But where, I ask, can you find a more deplorable and miserable object than the mind in ruins, tossed by its own rebellious principles, and distorted by the monstrously unequal development of its faculties? You will look in vain upon the earthquake, the volcano, or the hurricane, for those elements of the awful and terrible which are manifested in a community of men whose passions have trampled upon their principles, whose imaginations have overthrown the government of reason, and who are swept along by the torrent until all order and security are swallowed up and lost. Such a spectacle we have now been witnessing. We have seen the whole population of this place and vicinity yielding to the sway of their credulous fancies, allowing their passions to be worked up to a tremendous pitch of excitement, and rushing into excesses of folly and violence that have left a stain on their memory, and will awaken a sense of shame, pity, and amazement in the minds of their latest posterity.

There is nothing more mysterious than the self-deluding power of the mind, and there never were scenes in which it was more clearly displayed than the witchcraft prosecutions. Honest men testified, with perfect confidence and sincerity, to the most absurd impossibilities; while those who thought themselves victims of diabolical influence would actually exhibit, in their corporeal frames, all the appropriate symptoms of the sufferings their imaginations had brought upon them. Great ignorance prevailed in reference to the influences of the body and the mind upon each other. While the imagination was called into a more extensive and energetic action than at any succeeding or previous period, its properties and laws were but little understood: the extent of the connection of the will and the muscular system, the reciprocal influence of the nerves and the fancy, and the strong and universally pervading sympathy between our physical and moral constitutions, were almost wholly unknown. These important subjects, indeed, are but imperfectly understood at the present day.

It may perhaps be affirmed, that the relations of the human mind with the spiritual world will never be understood while we continue in the present stage of existence and mode of being. The error of our ancestors—and it is an error into which men have always been prone to fall, and from which our own times are by no means exempt—was in imagining that their knowledge had extended, in this direction, beyond the boundary fixed unalterably to our researches, while in this corporeal life.
