"The main task of dreams is to bring back a sort of “recollection” of the prehistoric, as well as the infantile world, right down to the level of the most primitive instincts. Such recollections can have a remarkably healing effect in certain cases, as Freud saw long ago. This observation confirms the view that an infantile memory gap (a so-called amnesia) represents a positive loss and its recovery can bring a positive increase in life and wellbeing."
