Rh in life and very primitive. But there is another equally fundamental and primitive emotion—fear. We may very well expect to find this emotion, as well as desire, subjacent to dream phenomena.

The wish-dream of the kind elaborately investigated by Freud may be accepted as, in what he terms its infantile form, extremely common, and, even in its symbolic forms, a real and not rare phenomenon. But it is impossible to follow Freud when he declares that the wish-dream is the one and only type of dream. The world of psychic life during sleep is, like the waking world, rich and varied; it can not be covered by a single formula. Freud's subtle and searching analytic genius has greatly contributed to enlarge our knowledge of this world of sleep. We may recognize the value of his contribution to the psychology of dreams while refusing to accept a premature and narrow generalization.
