In the past we have always assumed that the external world around us has represented reality, however confusing or uncertain, and that the inner world of our minds, its dreams, hopes, ambitions, represented the realm of fantasy and the imagination. These roles, it seems to me, have been reversed. The most prudent and effective method of dealing with the world around us is to assume that it is a complete fiction – conversely, the one small node of reality left to us is inside our own heads. Freud’s classic distinction between the latent and manifest content of the dream, between the apparent and the real, now needs to be applied to the external world of so-called reality.
