[Footnote 181: It is well known, and has often been pointed out (by Weygandt, Sante de Sanctis, Jewell, etc., and perhaps first by T. Beddoes in his _Hygeia_, 1803, vol. iii. p. 88), that while in childhood all the emotions of the past day are at once echoed in dreams, after adolescence, this is not so in the case of intense emotions, which do not emerge in dreams until after a more or less considerable interval. Marie de Manacéïne and Sante de Sanctis attribute this to exhaustion of the emotion which needs a period of repair and organic synthesis before it can repeat itself. Vaschide believed that we dream of recent events in shallow sleep and of remote events in deep sleep; this sounds plausible, but will scarcely account for all the phenomena.] [Footnote 182: Since the publication of my paper 'On Dreaming of the Dead,' several psychologists have returned to the subject. Thus Binet (_L'Année Psychologique_, 2nd year, issued in 1896, p. 848) gave a dream of his own, very similar to mine of the editor, in which a doctor, dead a month previously, is talking to him in his room. On Binet expressing surprise at seeing him, the doctor explains that he had only sent news of his death in order to see how many people would come to his funeral. Binet has also had two dreams, similar to that described on p. 200, in which he is walking in the country with a dead friend, who seems in good health, though the dreamer knows he will soon die. Foucault (_Le Rêve_, p. 128), who, in accordance with his own theory, regards my dream of the editor as belonging to the period of awakening, brings forward a dream of his own in which he saw his father, dead six months before, sitting in a chair; at first this seems to him a hallucination, but he finally accepts the vision as real. I have had a number of letters from people who have had dreams of this type. One correspondent, an anthropologist and folk-lorist of note, says that his dreams of dead friends are of the type of Mrs. F.'s. Professor Näcke writes that he has had such dreams (and see also his articles in the _Archiv für Kriminalanthropologie_, 1903, p. 307, and the _Neurologisches Centralblatt_, 1910, No. 13). One young lady states that, thirteen years after her mother's death, she still dreams of her as coming to life again or never having really died. I may add that this type of dream is admirably illustrated in a series of dreams concerning a dead friend, published in a letter from a lady to _Borderland_, January 1896, p. 51.] [Footnote 183: Gassendi, _Syntagma Philosophicum_, 1658, pars. 71, lib. viii.
