Dream speech (in German ''Traumsprache'') is internal speech in which errors occur during a dream. The term dream speech was coined by Emil Kraepelin in his 1906 monograph titled ''Über Sprachstörungen im Traume'' ("On Language Disturbances in Dreams"). The text discussed various forms of dream speech, outlining 286 examples. Dream speech is not to be confounded with the 'language of dreams', which refers to the visual means of representing thought in dreams. Three types of dream speech were considered by Kraepelin: disorders of word-selection (also called paraphasias), disorders of discourse (e.g. agrammatisms) and thought disorders. The most frequent occurring form of dream speech is a neologism. Kraepelin studied dream speech because it provided him with clues to the analoguous language disturbances of schizophrenic patients. Still in 1920 he stated that "dream speech in every detail corresponds to schizophrenic speech disorder." While Kraepelin was interested in the psychiatric as well as the psychological aspects of dream speech, modern researchers have been interested in speech production in dreams as illuminating aspects of cognition in the dreaming mind. They confirmed one of the findings of Kraepelin. ==The other Kraepelin== Dream speech opens up a new perspective on the psychiatrist Kraepelin, usually seen as the spiritual father of the DSM system of classification of psychiatric diseases and of biological psychiatry. However Kraepelin, one of the first disciples of Wilhelm Wundt, took a lifelong interest in psychology and even edited a journal ''Psychologische Arbeiten''. As one of the booklets of this journal a 104-pages article on dream speech appeared early in 1906, before the 105-pages monograph was published end 1906. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「dream speech」の詳細全文を読む スポンサード リンク
