We need to go deeper! Conceptual and methodological considerations on the depth of dream experience

This commentary aims to sharpen the conceptual distinction between the breadth and the depth of dream experience. I discuss several possible readings and argue that the best one construes breadth and depth as distinct but complimentary research strategies distinguished not just by the kinds of evidence they rely on, but also by the degree to which different types of data are integrated and focused on the same experiential episode. I identify promising candidates for depth approaches and challenges for future research.
