Those dreams which occur in very deep sleep, and in the early part of the night, are not so likely to be remembered as those which happen toward morning, when the sleep is less profound; hence the popular notion that our morning dreams--which are always best remembered--are likely to prove true. Then, again, the imagery of some dreams is more striking, and actually makes a deeper impression than the incidents of other dreams. We are told by Sir Humphrey Davy, that, on one occasion, a dream was so strongly impressed upon his eye, that even after he had risen and walked out, he could not be persuaded of its unreal nature, until his friends convinced him of its impossibility. The effect of some dreams upon children is very remarkable; they are, it is believed, more liable to dreams of terror than grown persons, which may be accounted for by their being more subject to a variety of internal complaints, such as teething, convulsions, derangement of the bowels, &c.; added to which, their reasoning faculties are not as yet sufficiently developed to correct such erroneous impressions. Hence, sometimes, children appear, when they awake, bewildered and distressed, and remain for a considerable period in a state of agitation almost resembling delirium. The incidents which are conceived in dreams are indeed not unfrequently confounded by adults with real events; hence, we often hear people, in alluding to some doubtful circumstance, exclaim, "Well! if it be not true, I certainly must have dreamed it." We confess we have ourselves been puzzled in this way; the spell may be broken; but the impression made by the delusion still clings to us; its shadow is still thrown across our path.
