“Intermittent fever is often announced, several days before any of the recognized symptoms set in, by persistent dreams of terrifying character. I have experienced this in my own person, and heard it confirmed by other sufferers on the African Coast. The following case of morbid dreaming ushering in yellow fever, I subjoin in the words of the gentleman to whom it occurred, himself a medical man holding a high official position on the Gold Coast where it occurred. “‘In the early part of 1840, I was an inmate of Cape Coast Castle, and as some repairs were then being made in the castle, the room assigned to me was that in which the ill-fated L. E. L. (Mrs. Maclean), the wife of the governor of Cape Coast, had been found dead, poisoned by prussic acid, not very long previously. I had known her in London, and had been intimately acquainted with her history and much interested in it. Her body had been found on the floor near the door and in front of a window. After a fatiguing excursion to some of the adjoining British settlements on the Coast, having retired to rest, I awoke disturbed by a dream of a very vivid character, in which I imagined that I saw the dead body of the lady who had died in that chamber lying on the floor before me. On awaking the image of the corpse kept possession of my imagination. The moon was shining brightly into the part of the room where the body had been found, and there, as it seemed to me on awaking, it lay pale and lifeless as it appeared to me in my dream. “‘After some minutes I started up, determined to approach the spot where the body seemed to be. I did so, not without terror, and walking over the very spot on which the moon was shining, the fact all at once became evident and obvious that no body was there--that I must have been dreaming of one. I returned to bed, and had not long fallen asleep when the same vivid dream recurred; the same waking disturbance occurring while awake. As long as I lay gazing on the floor I could not dispossess my mind of that appalling vision; but when I started up and stood erect it vanished at the first glance. “‘Again I returned to bed, dozed, dreamt again of poor L. E. L.’s lamentable end, and of her remains in the same spot; again awoke, and arose with the same strange results.
