as though we had been dreaming the whole night, although we cannot say what. I do not, however, think it necessary to assume that, up to the time of becoming conscious, the dream processes really follow the temporal sequence which we have described, viz. that there is first the transferred dream-wish, then the distortion of the censor, and consequently the change of direction to regression, and so on. We were forced to form such a succession for the sake of description; in reality, however, it is much rather a matter of simultaneously trying this path and that, and of emotions fluctuating to and fro, until finally, owing to the most expedient distribution, one particular grouping is secured which remains. From certain personal experiences, I am myself inclined to believe that the dream-work often requires more than one day and one night to produce its result; if this be true, the extraordinary art manifested in the construction of the dream loses all its marvels. In my opinion, even the regard for comprehensibility as an occurrence of perception may take effect before the dream attracts consciousness to itself. To be sure, from now on the process is accelerated, as the dream is henceforth subjected to the same treatment as any other perception. It is like fireworks, which require hours of preparation and only a moment for ignition.
Through the dream-work the dream process now gains either sufficient intensity to attract consciousness to itself and arouse the foreconscious, which is quite independent of the time or profundity of sleep, or, its intensity being insufficient it must wait until it meets the attention which is set in motion immediately before awakening. Most dreams seem to operate with relatively slight psychic intensities, for they wait for the awakening. This, however, explains the fact that we regularly perceive something dreamt on being suddenly aroused from a sound sleep. Here, as well as in spontaneous awakening, the first glance strikes the perception content created by the dream-work, while the next strikes the one produced from without.
But of greater theoretical interest are those dreams which are capable of waking us in the midst of sleep. We must bear in mind the expediency elsewhere universally demonstrated, and ask ourselves why the dream or the unconscious wish has
