The proposal that the process of conceptualization in the major psychologies of the twentieth century is inseparable from the experiences of their founders as readers of literature, especially "dream" literature, may still be met with defensive incredulity by practitioners in both disciplines. This chapter offers a contribution to oneiro-critics which seeks to raise awareness of its past, assess its present state, and proposes a guide for further study. It explores the wealth of material, selecting for emphasis certain dream episodes, authors, and literary texts which can be fruitfully consulted by the oneirophile. The chapter also explores the interrelation of dream and literature: dreams in literary texts; literary texts as dreams; the dreamed text; the literariness of dream treatises; the dreamlikeness of literary texts. It describes the new climate and the resulting interpenetration of dreams and texts.
