paragnesia is incorrectly written, and should be written as "reduplicative" being its meaning:
Of Greek origin: Hi: ( prefix ) next to, by, between, over, against, abnormally and mnesis mneseos: memory, memory: abnormal memory. It is an alteration of the memory in which the subject believes to have lived or experienced new situations. Psychologists speak of the " déjà vu: already seen " to designate this experience that seems to be very common. This French phrase was coined by the French from the beginning of the century XX Emile Boirac psychologist in his book "L " l'avenir des sciences psychiques ": the future of psychic Sciences. Anyway there are many kinds of paramnesias, some much more severe than the one described, such as those related to head injuries, brain bleeding, tumors, or psychiatric disorders.
