We come now to a more important difference, which includes the principle and has a characteristic apparently essentially distinguishing the dream--its looseness, disorder, inconstancy, and incoherence. In the dream visions succeed one another without connection; no law determines their order; an unrestricted fancy reigns among them, and the normal is broken up in them at every point. We are transported instantaneously from one country to another. We pass without transition from childhood to age, and causes have the strangest effects. The most essential laws of thought are constantly violated. There are facts without any causes, metamorphoses, magical disappearances. Even the absurd is realized, and the "principle of contradiction" does not seem to be any more respected than the others. We are at the same time in two places; we pronounce words, we hold conversations of which we can not when we wake recover the thread, so strange is their logic, so fugitive the sense, and so fanciful the combination. A practiced psychologist, M. Delbœuf, succeeded in taking down in the morning the last phrase of a book which he had been reading in a dream, and which had seemed then remarkably lucid. Here it is: "The man raised by the woman and separated by aberrations pushes facts disengaged by the analysis of the tertiary nature into the way of progress." Is this distinction, then--that the dream is incoherent and the real rational--any more just than the others? It is doubtful if it is. There are rare dreams in which everything proceeds in a regular and natural way; and, on the other hand, reality is not always exempt from capriciousness and improbability. But to me the capital objection to the distinction is that it is illusory, and the contrast between the disorder of dreams and the coherence of the real is only apparent. The dream, it is true, appears disordered to us, but that is when we are awake. An essential point which we always ignore is that _while we are dreaming_ everything seems simple and normal and regular to us. We are not at all astonished at what happens. We find it all right to be in two countries at the same time, and we understand very well how one person can be changed into another. The conversations we have--those which are utterly unthinkable when we are awake--usually appear to us marvelously lucid, and we admire the ease, the _verve_, and the luminous continuity of our words. We enjoy that moving with so much suppleness and precision among ideas; our demonstrations are infinitely convincing; and it is perhaps in the dream that we have the most perfect sense of evidence.
