Abstract
<jats:title>Abstract</jats:title> <jats:p>Despite the universal nature and significance of dreaming, the psychological sciences have had a historically uneasy relationship with dreams as a topic of study. The past three decades, however, have seen this wheel turn again, with advances in cognitive research provoking a reawakening of sorts. Such research is provoking new questions not just about dreaming but also its relevance for consciousness, the self, social cognition, and our relationship with reality. This introduction outlines how the volume aims at answering these questions by grouping them under four key clusters (narrativity, permeability, immersivity, and reportability), in an interdisciplinary framework encompassing not just the psychological sciences but the full breadth of the arts, humanities, and social sciences. It also contextualizes this volume within the history of an interdisciplinary project at Durham University, Threshold Worlds: Dreams, Narrative, and Liminal Cognition, which was an incubator for the ideas and directions that structure the volume. The project included the design and implementation of a novel interdisciplinary survey, which is reported for the first time in this volume, including reflections and analysis from several of the contributing authors.</jats:p>
