Anamnesis is a kind of unforgetting - in theology/ philosophy it can means a recollection of suppressed or blocked truth and reality, that is triggered by some kind of 'releasing stimulus'.
It was an aspect of Gnosticism* - as with the Hymn of the Pearl; an allegory for this mortal life in which the son of a king is sent to earth to retrieve a pearl, but forgets his mission (among the temptations of life) until reminded of it by a letter.
Supposedly, historically, this was Not intended to mean Jesus; but maybe it did originally - to some extent.
At any rate it fits my understanding that Jesus (having being incarnated specifically to bring resurrection to Men, did not 'remember' his mission; because, presumably, the time was not right - or the right 'trigger' had not been arranged.
Thus Jesus did not become divine (i.e. attain to his divine creative powers), until his baptism by John; when John recognized who Jesus was, and the spirit of God provided signs to that effect.
*Gnosticism was mostly wrong, and wrong in several fundamental assumptions; but, of course, everything that catches-on and effects the world has some truth in it - even when that is distorted, partial or inverted.
