There is another class of dreams which would appear to be much more extraordinary than these of a Retrospective Character, to wit: those in which the dreamer appears to take cognizance of incidents which are occurring at a distance, which may be designated Dreams of COINCIDENCE. In the "Memoirs of Margaret de Valois" we read, that her mother, Catherine de Medicis, when ill of the plague at Metz, saw her son, the Duc d'Anjou, at the victory of Jarnac, thrown from his horse, and the Prince de Condé dead--events which happened exactly at that moment. Dr. Macnish relates, as the most striking example he ever met with of the co-existence between a dream and a passing event, the following melancholy story: Miss M., a young lady, a native of Ross-shire, was deeply in love with an officer who accompanied Sir John Moore in the Peninsular War. The constant danger to which he was exposed had an evident effect upon her spirits. She became pale and melancholy in perpetually brooding over his fortunes; and, in spite of all that reason could do, felt a certain conviction that, when she last parted from her lover, she had parted with him forever. In a surprisingly short period her graceful form declined into all the appalling characteristics of a fatal illness, and she seemed rapidly hastening to the grave, when a dream confirmed the horrors she had long anticipated, and gave the finishing stroke to her sorrows. One night, after falling asleep, she imagined she saw her lover, pale, bloody, and wounded in the breast, enter her apartment. He drew aside the curtains of the bed, and, with a look of the utmost mildness, informed her that he had been slain in battle, desiring her, at the same time, to comfort herself, and not take his death too seriously to heart. It is needless to say what influence this vision had upon a mind so replete with woe. It withered it entirely, and the poor girl died a few days afterward, but, not without desiring her parents to note down the day of the month on which it happened, and see if it would not be confirmed, as she confidently declared it would. Her anticipation was correct, for accounts were shortly afterward received that the young man was slain at the battle of Corunna, which was fought on the very day of the night of which his betrothed had beheld the vision. It is certainly very natural to suppose that there must be some mysterious connection between such a dream and the event which appears to have simultaneously taken place--but, upon reflecting further upon the subject, we shall find that the co-existence is purely accidental. If, as Sir Walter Scott observed, any event, such as the death of the person dreamt of, chance to take place, so as to correspond with the nature and time of the apparition, the circumstance is conceived to be supernatural, although the coincidence is one which must frequently occur, since our dreams usually refer to the accomplishment of that which haunts our minds when awake, and often
