It is a regular task in psycho-analytic treatment to fill in the blank in infantile memories, and, in so far as the treatment is successful to any extent at all (very frequently, therefore) we are enabled to bring to light the content of those early years long buried in oblivion. These impressions have never really been forgotten, but were only inaccessible and latent, having become part of the unconscious. But sometimes it happens that they emerge spontaneously from the unconscious, and it is in connection with dreams that this happens. It is clear that the dream-life knows the way back to these latent, infantile experiences. Many good illustrations of this are to be found in psycho-analytical literature, and I myself have been able to furnish a contribution of the sort. I once dreamt in a particular connection of someone who had evidently done me a service and whom I saw plainly. He was a one-eyed man, short, fat and high-shouldered; from the context I gathered that he was a doctor. Fortunately I was able to ask my mother, who was still living, what was the personal appearance of the doctor who attended us at the place where I was born and which I left at the age of three; she told me that he had only one eye and was short, fat and high-shouldered; I learnt also of the accident which was the occasion of this doctor’s being called in and which I had forgotten. This command of the forgotten material of the earliest years of childhood is thus a further ‘archaic’ feature of dreams.
