Always rich in heterogeneous suggestions, Merleau-Pontian reflection does not fail to address the status of oneiric experience, which is as complex as it is neglected or even trivialized in phenomenological studies. Although it is sometimes taken into consideration, notably in Sartrean analyses, this is only to reconduct it to the activity of the imagining consciousness. This contribution thus proposes to bring out the innovative character of Merleau-Ponty’ dream framework. After outlining the Sartrean considerations, Merleau-Ponty’s positions are briefly presented. Ultimately at (...) stake is showing to what extent the advancement of a sincerely new conception of the dream, together with the rejection of the Sartrean positions, can only take place through reading the work of Ludwig Binswanger. Binswanger’s analyses of oneiric space allow an original approach to dreaming as an authentic experience that reveals a primary spatiality and a more originary mode of existence, thereby testifying to a form of passivity inherent in consciousness. Dreaming thus becomes fundamental for understanding our being-in-the-world in general and, consequently, also for understanding wakefulness. (shrink)
