Of all the human behaviors anthropologists consider, perhaps the most conceptually challenging are those that cannot by directly observed. This volume draws from rich ethnographic data to offer theoretical and methodological tools for mapping the intersections between two such behaviors: dreaming and imagination. Although Western perspectives tend to cast these as personal experiences contained within individual minds, each contributor explores diverse cultural and historical contexts to demonstrate how these behaviours are always in some sense cultural and influenced by social others. The cross-cultural approach suggests theoretical flexibility and expands the study of imagination across multiple disciplines.
