criptomnesia 1
It is said of the existence of hidden memories in consciousness. That is, the person does not know that he has memories and that he does not know or does not remember where he got them from or how they were generated. This can cause problems for the person who suffers from them, as it can occur in social situations where the person usually gives news, information, writings, meanings, etc. That have already been announced by herself or by someone else before. It is, therefore, a form of unconscious plagiarism in which a person thinks they have an original idea, but in reality it is something they have previously seen, read or heard.
