The Book of Dreams and Ghosts

Probably we do a good deal of reasoning in sleep. Professor Hilprecht, in 1882-83, was working at a translation of an inscription wherein came Nabu--Kudurru--usur, rendered by Professor Delitzsch "Nebo protect my mortar-board". Professor Hilprecht accepted this, but woke one morning with his mind full of the thought that the words should be rendered "Nebo protect my boundary," which "sounds a deal likelier," and is now accepted. I myself, when working at the MSS. of the exiled Stuarts, was puzzled by the scorched appearance of the paper on which Prince Charlie's and the king's letters were often written and by the peculiarities of the ink. I woke one morning with a sudden flash of common-sense. Sympathetic ink had been used, and the papers had been toasted or treated with acids. This I had probably reasoned out in sleep, and, had I dreamed, my mind might have dramatised the idea. Old Mr. Edgar, the king's secretary, might have appeared and given me the explanation. Maury publishes tales in which a forgotten fact was revealed to him in a dream from the lips of a dream-character (Le Sommeil et les Reves, pp. 142-143. The curious may also consult, on all these things, The Philosophy of Mysticism, by Karl du Prel, translated by Mr. Massey. The Assyrian Priest is in Proceedings, S.P.R., vol. xii., p. 14). On the same plane as the dreams which we have been examining is the waking sensation of the deja vu. "I have been here before, But when or how I cannot tell."
