Beta-elements are not amenable to use in dream thoughts but are suited for use in projective identification. They are influential in producing acting out. These are objects that can be evacuated or used for a kind of thinking that depends on manipulation of what are felt to be things in themselves as if to substitute such manipulations for words or ideas... Alpha-function transforms sense impressions into alpha-elements which resemble, and may in fact be identical with, the visual images with which we are familiar in dreams, namely, the elements that Freud regards as yielding their latent content when the analyst has interpreted them. Failure of alpha-function means the patient cannot dream and therefore cannot sleep. As alpha-function makes the sense impressions of the emotional experience available for conscious and dream—thought the patient who cannot dream cannot go to sleep and cannot wake up. (1962, pp. 6–7)
