Cryptamnesia

How much is cryptamnesia-confabulation, how much frontal-lobe indifference-equalisation, how much some strange schizophrenic disintegration and shattering-flattening?

And although [Sigmund] Freud claimed that others’ ideas were of no use to him unless they came at a time when he was ready for them, he proved enormously susceptible to their influence and even noted his own tendency to ‘cryptamnesia’, by which he ‘unconsciously’ contrived to forget his intellectual debts.

While apparent regressions into past lives can often easily be shown to be constructions based on cryptamnesia[…], this is by no means always the case. In 1987, one hypnotherapy client experienced an apparent 'past life' as a submariner who died with his ship in 1942; he provided detailed names and dates that could be confirmed from the records of the naval base where he was supposed to have served[…]. If we insist on a Darwinian account, these phenomena must be examples of cryptamnesia, suggestion or fraud.
