Cryptomnesia - a type of memory disorders in which other people's ideas seem to be his own man

Cryptomnesia - this type of memory disorders in which a person can not remember when it was this or that event - in a dream or in reality; he wrote a poem, or simply remember once read; whether he was at the concert of a famous musician or only heard talk about this. In other words, forget the source of any information. Other people's ideas, other people's work, once perceived by man, after a while realized as his.

The term "cryptomnesia" was proposed by a professor of psychology Theodore Flournoy, shortly after they study the medium Helen Smith, who by means of so-called "automatic writing" telling us about his previous life and about his contacts with the Martians. T. Flournoy concluded that the language of "Martian" letters close to her native French, and that her revelations are nothing more than subconscious imagination, based largely on the forgotten sources.
