one of its constituent elements.  It is confronted, however, by the censor, which is still active, and to the influence of which it now succumbs.  It now takes on the distortion for which the way has already been paved by its transference to the recent material.  Thus far it is in the way of becoming something resembling an obsession, delusion, or the like, i.e. a thought reinforced by a transference and distorted in expression by the censor.  But its further progress is now checked through the dormant state of the foreconscious; this system has apparently protected itself against invasion by diminishing its excitements.  The dream process, therefore, takes the regressive course, which has just been opened by the peculiarity of the sleeping state, and thereby follows the attraction exerted on it by the memory groups, which themselves exist in part only as visual energy not yet translated into terms of the later systems.  On its way to regression the dream takes on the form of dramatization.  The subject of compression will be discussed later.  The dream process has now terminated the second part of its repeatedly impeded course.  The first part expended itself progressively from the unconscious scenes or phantasies to the foreconscious, while the second part gravitates from the advent of the censor back to the perceptions.  But when the dream process becomes a content of perception it has, so to speak, eluded the obstacle set up in the Forec. by the censor and by the sleeping state.  It succeeds in drawing attention to itself and in being noticed by consciousness.  For consciousness, which means to us a sensory organ for the reception of psychic qualities, may receive stimuli from two sources—­first, from the periphery of the entire apparatus, viz. from the perception system, and, secondly, from the pleasure and pain stimuli, which constitute the sole psychic quality produced in the transformation of energy within the apparatus.  All other processes in the system, even those in the foreconscious, are devoid of any psychic quality, and are therefore not objects of consciousness inasmuch as they do not furnish pleasure or pain for perception.  We shall have to assume that those liberations of pleasure and pain automatically regulate the outlet of the occupation processes.  But in order to make possible more delicate functions, it was later found necessary to render the course of the presentations more independent of the manifestations of pain.  To accomplish this the Forec. system needed some qualities of its own which could attract consciousness, and most probably received them through the connection of the foreconscious processes with the memory system of the signs of speech, which is not devoid of qualities.  Through the qualities of this system, consciousness, which had hitherto been a sensory organ only for the perceptions, now becomes also a sensory organ for a part of our mental processes.  Thus we have now, as it were, two sensory surfaces, one directed to perceptions and the other to the foreconscious mental processes.
