"The latent content of dreams consists of: 1. Dynamically unconscious wishes (id impulses) prevented by the censorship (the defences of the ego) from reaching consciousness or even the system preconscious during waking life. Several wishes may be present in the same dream: 'Dreams frequently seem to have more than one meaning. Not only, as our examples have shown, may they include several wishfulfilments one alongside the other; but a succession of meanings or wish-fulfilments may be superimposed on one another, the bottom one being the fulfilment of a wish dating from earliest childhood. And here again the question arises whether it might not be more correct to assert that this occurs "invariably" rather than "frequently"."
