to the motor end because of the fact just mentioned. We now enter both systems in our scheme, and express by the names given them their relation to consciousness.
Fig. 3.
The last of the systems at the motor end we call the foreconscious in order to denote that exciting processes in this system can reach consciousness without any further detention provided certain other conditions be fulfilled, e.g., the attainment of a certain intensity, a certain distribution of that function which must be called attention, and the like. This is at the same time the system which possesses the keys to voluntary motility. The system behind it we call the unconscious because it has no access to consciousness except through the foreconscious, in the passage through which its excitement must submit to certain changes.
In which of these systems, now, do we localise the impulse to the dream formation? For the sake of simplicity, let us say in the system Unc. To be sure we shall find in later discussions that this is not quite correct, that the dream formation is forced to connect with dream thoughts which belong to the system of the foreconscious. But we shall learn later, when we come to deal with the dream-wish, that the motive power for the dream is furnished by the Unc., and, owing to this latter movement, we shall assume the unconscious system as the starting-point of the dream formation. This dream impulse, like all other thought structures, will now strive to continue itself in the foreconscious, and thence to gain admission to consciousness.
Experience teaches us that the road leading from the foreconscious to consciousness is closed to the dream thoughts during the day by the resistance of the censor. At night the
