In this connection it is well to notice that it is a common observation that not only the affect of emotion but that of _feeling_ also may emerge from the subconscious into consciousness and color the attitude of the personal consciousness. This may be demonstrated by hypnotic procedures. When in hypnosis complexes of ideas with strong feeling tones, whether of pleasure or displeasure, of exaltation or depression, are suggested, the subject after awakening experiences these same feeling tones which dominate the personality. The subject then feels pleasantly exalted or unpleasantly depressed, as the case may be, without knowing the reason why. In alternating personalities the same phenomena may sometimes be observed. In the case of Miss B. the feeling tones which dominated the one personality invaded the consciousness of the other personality, often causing considerable distress after the alternation had occurred and although there was amnesia for all that had gone before.[181] Thus BIV complained of the feelings of depression from which BI shortly before had suffered, although her own ideas were far from being of a depressing nature. This depression welled up from the unconscious. It was in consequence of this phenomenon that BIV wrote: “BI’s constant grieving wears on my nerves. It is harder to endure than one would believe possible. I would rather give and take with Sally—a thousand times rather.” Likewise when a subject has feelings of unpleasantness and depression which he cannot explain it is easy in certain subjects to demonstrate the concurrence of coconscious ideas with these feeling tones. The affect in such cases emerges into consciousness, though the subject is unaware of the coconscious ideas. Correspondingly the feelings may be those of pleasantness and exaltation. The demonstration of coconscious processes as the sources of the conscious feelings of course can only be made in subjects in whom memories of coconscious processes can be evoked. In such subjects I have observed the phenomena on almost numberless occasions. But it can be provoked in almost any good hypnotic subject. To awake pleasurable and exalting feelings, to substitute them for their opposite when such are present, belongs to therapeutic art. The skillful therapeutist endeavors to provoke the former by the various procedures at his command. The important principle underlying such procedures is that the feeling tones pertaining to ideas may still invade the personal consciousness after the ideas have become dormant in the unconscious.
