I am aware that this conception cannot be generally demonstrated, but I maintain nevertheless that it can be frequently demonstrated, even when it was not suspected, and that it cannot be generally refuted. The wish-feelings which remain from the conscious waking state are, therefore, relegated to the background in the dream formation. In the dream content I shall attribute to them only the part attributed to the material of actual sensations during sleep. If I now take into account those other psychic instigations remaining from the waking state which are not wishes, I shall only adhere to the line mapped out for me by this train of thought. We may succeed in provisionally terminating the sum of energy of our waking thoughts by deciding to go to sleep. He is a good sleeper who can do this; Napoleon I. is reputed to have been a model of this sort. But we do not always succeed in accomplishing it, or in accomplishing it perfectly. Unsolved problems, harassing cares, overwhelming impressions continue the thinking activity even during sleep, maintaining psychic processes in the system which we have termed the foreconscious. These mental processes continuing into sleep may be divided into the following groups: 1, That which has not been terminated during the day owing to casual prevention; 2, that which has been left unfinished by temporary paralysis of our mental power, _i.e._ the unsolved; 3, that which has been rejected and suppressed during the day. This unites with a powerful group (4) formed by that which has been excited in our Unc. during the day by the work of the foreconscious. Finally, we may add group (5) consisting of the indifferent and hence unsettled impressions of the day.
