=Evidence obtained from dreams.=—Another not uncommon mode in which forgotten experiences are recovered is through dreams. The content of the dream may, as Freud has shown, be a cryptic and symbolical expression or representation of the experience,[21] or a visualized representation or obvious symbolism, much as a painted picture may be a symbolized expression of an idea,[22] or it may be a realistic reproduction in the sense that the subject lives over again the actual experience. A relative of mine gave me a very accurate description of a person whom she had never seen from a dream in which he appeared. After describing his hair, eyes, contour of face, mouth, etc., she ended with the words, “He looks like a cross between a Scotchman and an Irishman.” After she had most positively insisted that she had never seen this person or heard him described—against my protest to the contrary—I reminded her that I had myself described him to her only a few days before in the identical words, ending my description with the remark, “He looks like a cross between a Scotchman and an Irishman.” Even then she could not recall the fact. Von Bechterew has recorded the case of a man who frequently after hearing an opera dreamed the whole opera through.[23] One subject of mine frequently dreamed over again in very minute detail, after an interval of eight or nine months, the scenes attending the deathbed of a relative. Indeed, in the dream she realistically lived them again in a fashion similar to that of hypnotic dreams such as I have related. Although she had not forgotten these scenes it is highly improbable that she could have voluntarily recalled them, particularly after the lapse of so long a time, without the aid of the dream, so rich was it in detail, with each event in its chronological order.
