Perhaps my sense of reality is not very highly developed, perhaps I lack a sound and reassuring instinct for the solid facts of our earthly existence; I can’t always tell memories from dreams, and often I mistake dreams, coming to life again in colours, smells, sudden associations, with the eerie secret certainty of a past life from which time and space divide me no differently and no better than a light sleep in the early hours.
