Recognizing the importance of Bion's insight that access to reverie enables the mother to initiate in her infant the internalization of her capacity for transformative thought in response to lived emotional experience, and recognizing the presence of a good-enough internal object may not be assumed, the author proposes the primary task of dream thinking is the internalization and nourishment of the good internal object throughout life. The author reviews Ogden's comparison of Winnicott's “holding environment” and Bion's “container/contained” theories and then explores the application of this hypothesis through study of a clinical example and of selections of the lyric poetry of William Wordsworth.
