[Chronicles of Narnia] What is the mental state of the four main characters after they turn back into children?

Do they remember being adults? If so what's it like for Edmund and Lucy who are pre-adolescent?

They eventually forget all of their time in Narnia, thinking of it as having been a game they played together as children, rather than actual events that happened.  The older they get, the more they're sure it was just make-believe.

Susan gets hit with this especially hard, becoming unable to return to Narnia for the Last Battle because she has become too old, and stopped believing it ever existed.
