shall mention some circumstances here, which have occurred to myself and to others, which will place this subject in a clearer point of view. The first case of this kind which I shall relate, I had from the mouth of a person of undoubted veracity, who never understood the nature of the hallucination; but who, to the day of his death, was convinced that he had received a supernatural visitation. Mr. T----, a dissenting minister, was on a journey in Suffolk, and slept at the house of a friend. He was desired by the master of the family not to disturb himself in the morning till he was called; supposing that he was fatigued and would require repose. Mr. T----, however, did not sleep very sound, he awoke often, and as it was in the summer season, and he had no watch with him, began to grow anxious about the time, as it had been long day-light: he thought, however, on what he had been told over night, and was expecting very shortly to be called to breakfast. He described himself as being awoke out of his sleep by hearing distinctly some person in an adjoining room get out of bed, and walk across the room to a door communicating with his own, which he heard opened, and a voice called to him, repeating distinctly his name, three times. He supposes that he immediately afterwards fell asleep, and did not wake till some time after, when, he observed, he had a paroxysm of Night-Mare; on recovering, however, from this, he instantly got up, supposing that he had overslept himself, and that the family would be waiting for him to breakfast. He was greatly surprised to find the doors and the windows of the house all close shut, and no one of the family stirring; it was in fact only five o’clock in the morning. He consequently returned to bed, and slept comfortably till breakfast was really announced to him. He related to the family the adventure which had occurred to him, which seemed to cause little surprize, but produced tears from some of them: they informed him that nobody slept in the adjoining room, but that it had formerly been occupied by their son, who had been several years at sea; that they had heard nothing of him for some months, and entertained no doubt of his being dead, and this circumstance served to confirm them in their opinion, and left no doubt in the minds of all present that Mr. T---- had received a supernatural visitation. Mr. T---- was himself of the same opinion to the day of his death, although the young gentleman whose fate was considered so well ascertained, proved in the sequel to be alive. This, I am convinced, was a genuine case of Night-Mare, as I have very frequently experienced something very similar to it, as I shall explain by and by.
