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) Bizarre object Bizarre objects, according to Bion, are impressions of external objects which, by way of projective identification, form a "screen" that's imbued with characteristics of the subject's own personality; they form part of his interpretation of object relations theory. Bion saw psychotic attacks on the normal linking between objects as producing a fractured world, where the patient felt themselves surrounded by hostile bizarre objects—the by-products of the broken linkages. Such objects, with their superego components, blur the boundary of internal and external, and impose a kind of externalised moralism on their victims. They can also contain ego-functions that have been evacuated from the self as part of the defence against thinking, sensing, and coming to terms with reality: thus a man may feel watched by his telephone, or that the music player being listened to is in fact listening to him in turn. Later developments Hanna Segal considered bizarre objects more difficult to re-internalise than either good or bad objects due to their splintered state: grouped together in a mass or psychic gang, their threatening properties may contribute to agoraphobia. Knowledge, love and hate Successful application of alpha-function leads to "the capacity to tolerate the actual frustration involved in learning ("K") that [Bion] calls 'learning from experience. The opposite of knowledge "K" was what Bion termed "−K": "the process that strips, denudes, and devalues persons, experiences, and ideas." Both K and −K interact for Bion with Love and Hate, as links within the analytic relationship. "The complexities of the emotional link, whether Love or Hate or Knowledge [L, H, and K – the Bionic relational triad]" produce ever-changing "atmospheric" effects in the analytic situation. The patient's focus may wish to be "on Love and Hate (L and H) rather than the knowledge (K) that is properly at stake in psychoanalytic inquiry." For Bion, "knowledge is not a thing we have, but a link between ourselves and what we know ... K is being willing to know but not insisting on knowledge." By contrast, -K is "not just ignorance but the active avoidance of knowledge, or even the wish to
