A belief in the supernatural origin of dreams sometimes leads to their fulfilment. A person dreams of approaching sickness. His fears and his imagination hasten on the calamity. A general, on the eve of battle, dreamed of a defeat. His belief in dreams deprived him of courage, and, of course, the enemy conquered. We have on record the case of a German student, who dreamed that he was to die at a certain hour on the next day. His friends found him in the morning making his will and arranging his affairs. As the time drew near, he had every appearance of a person near his end. Every argument was used to shake his belief in the supernatural origin of his dream, but all to no effect. At last, the physician contrived to place the hands of the clock beyond the specified hour, and by this means saved the student's life. There are instances on record where death has actually ensued in consequence of such a belief. It has been produced by the wonderful power the mind possesses over the body. And there can be no doubt that believers in dreams often take the most direct means to hasten their fulfilment. The apparent fulfilment of dreams is sometimes merely accidental. The dream happens, and the event dreamed of soon follows; but the coincidence is altogether fortuitous. A member of Congress informed a friend that he frequently dreamed of the death of some one of his children, while residing at Washington. The whole scene would appear before him--the sickness, the death, and the burial; and this too several times the same night, and on successive nights. His anxiety for his family caused his dreams. Now, it would have been nothing strange if a member of his family had died. But in this particular instance it was not the case. In this way, however, we are always dreaming of our absent relatives, and it would be singular if a death did not sometimes occur at the time of the dream. So on all other subjects. One event may follow the other, and yet the coincidence be perfectly accidental. There are occasionally some amusing cases of this kind. A person dreamed three times in one night that he must turn to the seventh verse of the fifth chapter of Ecclesiastes, and he would find important instruction. He arose in the morning, and, referring to the specified passage, found these words: "_In the multitude of dreams there are divers vanities._" Finally, the occasion of some dreams seems as yet inexplicable. But as we can account for so large a portion of them, it is rational to believe that the causes of the few mysterious ones will be hereafter satisfactorily explained. We think we are safe in believing that all our dreams are caused by some principle of our intellectual or animal nature. Let us then pay no further regard to them than to aim by a pure conscience before God, and a careful attention to our stomachs and health, to have them refreshing and agreeable. CHAPTER IV.
