Similarly Spitta,[64] who seems to think that it is only in our attempt to reproduce the dream that we put in order the loosely associated dream elements: “To make connection out of disconnection, that is, to add the process of logical connection which is absent in the dream.” As we do not at present possess any other objective control for the reliability of our memory, and as indeed such a control is impossible in examining the dream which is our own experience, and for which our memory is the only source, it is a question what value we may attach to our recollections of dreams. (_e_) _The Psychological Peculiarities of Dreams._—In the scientific investigation of the dream we start with the assumption that the dream is an occurrence of our own psychic activity; nevertheless the finished dream appears to us as something strange, the authorship of which we are so little forced to recognise that we can just as easily say “a dream appeared to me,” as “I have dreamt.” Whence this “psychic strangeness” of the dream? According to our discussion of the sources of dreams we may suppose that it does not depend on the material reaching the dream content; because this is for the most part common to the dream life and waking life. One may ask whether in the dream it is not changes in the psychic processes which call forth this impression, and may so put to test a psychological characteristic of the dream. No one has more strongly emphasized the essential difference between dream and waking life, and utilised this difference for more far-reaching conclusions, than G. Th. Fechner[25] in some observations in his _Elements of Psychophysic_ (p. 520, part 11). He believes that “neither the simple depression of conscious psychic life under the main threshold,” nor the distraction of attention from the influences of the outer world, suffices to explain the peculiarities of the dream life as compared with the waking life. He rather believes that the scene of dreams is laid elsewhere than in the waking presentation life. “If the scene of the psychophysical activity were the same during the sleeping and the waking states, the dream, in my opinion, could only be a continuation of the waking ideation maintaining itself at a lower degree of intensity, and must moreover share with the latter its material and form. But the state of affairs is quite different.” What Fechner really meant has never been made clear, nor has anybody else, to my knowledge, followed further the road, the clue to which he indicated in this remark. An anatomical interpretation in the sense of physiological brain localisations, or even in reference to histological sections of the cerebral cortex, will surely have to be excluded. The thought may, however, prove ingenious and fruitful if it can be referred to a psychic apparatus which is constructed out of many instances placed one behind another.
