DREAM AND CULTURE.--The function of the brain which is most influenced by sleep is the memory; not that it entirely ceases; but it is brought back to a condition of imperfection, such as everyone may have experienced in pre-historic times, whether asleep or awake. Arbitrary and confused as it is, it constantly confounds things on the ground of the most fleeting resemblances; but with the same arbitrariness and confusion the ancients invented their mythologies, and even at the present day travellers are accustomed to remark how prone the savage is to forgetfulness, how, after a short tension of memory, his mind begins to sway here and there from sheer weariness and gives forth lies and nonsense. But in dreams we all resemble the savage; bad recognition and erroneous comparisons are the reasons of the bad conclusions, of which we are guilty in dreams: so that, when we clearly recollect what we have dreamt, we are alarmed at ourselves at harbouring so much foolishness within us. The perfect distinctness of all dream-representations, which pre-suppose absolute faith in their reality, recall the conditions that appertain, to primitive man, in whom hallucination was extraordinarily frequent, and sometimes simultaneously seized entire communities, entire nations. Therefore, in sleep and in dreams we once more carry out the task of early humanity. 13. THE LOGIC OF DREAMS.--In sleep our nervous system is perpetually excited by numerous inner occurrences; nearly all the organs are disjointed and in a state of activity, the blood runs its turbulent course, the position of the sleeper causes pressure on certain limbs, his coverings influence his sensations in various ways, the stomach digests and by its movements it disturbs other organs, the intestines writhe, the position of the head occasions unaccustomed play of muscles, the feet, unshod, not pressing upon the floor with the soles, occasion the feeling of the unaccustomed just as does the different clothing of the whole body: all this, according to its daily change and extent, excites by its extraordinariness the entire system to the very functions of the brain, and thus there are a hundred occasions for the spirit to be surprised and to seek for the _reasons_ of this excitation;--the dream, however, is _the seeking and representing of the causes_ of those excited sensations,--that is, of the supposed causes. A person who, for instance, binds his feet with two straps will perhaps dream that two serpents are coiling round his feet; this is first hypothesis, then a belief, with an accompanying _mental_ picture and interpretation--" These serpents must be the _causa_ of those sensations which I, the sleeper, experience,"--so decides the mind of the sleeper. The immediate past, so disclosed, becomes to him the present through his excited imagination. Thus every one knows from experience how quickly the dreamer weaves into his dream a loud sound that he hears, such as the ringing of bells or the firing
