The cause of the dream is sometimes the cause of its fulfilment. For example, a person might think, in his waking moments, of writing a poem, and if it is strongly on his mind he is likely to dream of it. The dream may suggest some missing link or idea, and when he awakes he is better prepared to complete it. Belief in the supernatural origin of dreams is also the frequent cause of their fulfilment. If a person dreams of approaching sickness, and is superstitious, his fears and imagination are likely to hasten the calamity. There is recorded somewhere in history the case of a general who dreamed of a defeat, and, being superstitious, his courage deserted him, and the enemy conquered. There is also recorded the case of a German student, who dreamed that he was to die the next day at a certain hour. His friends found him next morning making a will and other preparations, and as the time drew near, he had every appearance of a person about to die. His friends used every argument to shake his belief in dreams, but to no purpose, and they were despairing of saving him, when the physician contrived to set the clock forward, and thus prolonged matters until the student's life was at last saved. There are several instances on record where death has actually ensued in consequence of the belief in the supernatural origin of dreams, and there is no doubt that believers in dreams often cause fulfilment by mental influence. It is true that there are instances on record where a person has dreamed of the death of a relative, and found that that relative had died at about the time of the dream, but these instances are rare and prove nothing. When it is considered that there are doubtless millions of instances where persons have dreamed of the death of relatives, when they have not died, the comparatively few cases where the dreams came true must be taken as mere coincidence. It is not a miracle for a dream of this kind to come true, but it would indeed be a miracle if one or more of such dreams did not come true, like the one that is recorded of a proud young divinity student who dreamed three times in one night that he must turn to the seventh verse of the fifth chapter of Ecclesiastes, where he would find important instructions. He arose in the morning, and turning to the specified passage, found this: "In the multitude of dreams there are divers vanities." The mental process by which the human mind arrived at the conclusion that dreams result from supernatural causes is due to the same propensity of the mind for the marvelous, and to that excess credulity which attributes all unusual or remarkable mental impressions to some external agency. The average mind is prone to reason out the causes of phenomena to the limit of its mental powers, and then, when it arrives at the point when it can go no farther, and can give no rational explanation, to attribute the phenomena to the supernatural.
