Analysis of information sources in references of the Wikipedia article "Kriptomnezi" in Turkish language version.
An early example of this occurred in 1874 with he medium William Stanton Moses, who communicated with the spirits of two brothers who had recently died in India. Upon investigation, it was discovered that one week prior to the séance, their obituary had appeared in the newspaper. This was of some importance because Moses's communications with the two spirits contained nothing that wasn't already printed in the newspaper. When the spirits were pressed for further information, they were unable to provide any. Researchers concluded that Moses had seen the obituary, forgotten it, and then resurfaced the memory during the séance.
The book of adventure stories as "source" was discovered by Carl Jung, who describes his find, and his subsequent belief that Nietzsche had "crpytomnesia," the concealed recollection of a textual memory, to his seminar of fellow depth psychologists who gathered once a week between 1934 and 1939 to analyze Thus Spoke Zarathustra. The piece of text "secretly crept up and reproduced itself" in "Of Great Events" (Z 2). Jung recognized the story about seamen stopping on an island to hunt rabbits, having read it in his grandfather's library. He wrote Elisabeth Forster-Nietzsche, who confirmed that she and Nietzsche had read the same book in their grandfather's library, when Nietzsche was eleven. This, Jung informed his Zarathustra seminar, "shows how the unconscious layers of the mind work." He added, "the absolute parallel is of course formed by the rabbits" (1218).
