Windt (2013) eloquently and compellingly presents an anti-skeptical approach to the use of subjective dream reports in empirical research (the “transparency view”). On this view, dream reports are “trustworthy sources of evidence about the occurrence and phenomenal character of experience during sleep, at least when gathered under ideal reporting conditions.” Her paper is an example of the changing tides in the cognitive neuroscience of consciousness, and is a welcome valorization of the utility of subjective reports. The long-standing distrust of verbal reports of private mental processes is gradually giving way to realization of the necessity for incorporating first-person reports into objective, third-person paradigms in mutually informing ways (Varela and Shear, 1999)—a methodology often embraced by the term “neurophenomenology” (Lutz and Thompson, 2003). But what are “ideal reporting conditions?” Taking Windt's “transparency view” as a starting point, we discuss a number of methodological considerations for neurophenomenological research on dreaming. We agree with Windt that it is crucial for empirical dream research to establish the extent to which dream reports are “transparent” accounts of subjective experiences; indeed, such transparency is the sine qua non for conducting meaningful qualitative and quantitative research on dream content. However, whereas dream experiences may be disclosed to the dreamer—or at least appear in the dreamer's memory—in a transparent way, important individual differences exist in introspective skills and in ability to articulate the breadth or depth of experience accurately in verbal or written form (Fleming et al., 2010; Sze et al., 2010; Fox et al., 2012). We may need to ask then, on both practical and epistemological levels, whether we wish to uncover what is “typical” in dreams of a certain socio-cultural population (the “breadth” of dreaming), or what is “possible” in the dream state (the “depth” of dreaming). In light of this distinction, the “ideal conditions” for reporting dreams may well be different depending on whether the purpose of a study is to assess breadth or depth of dream experience. Accordingly, and to further integrate dream studies within the nascent neurophenomenological framework, we outline two methodological elements that support more reliable elicitation, collection and analysis of dream reports: (1) specific and rigorous laboratory conditions for dream collection; and (2) introspective training and/or solicitation of “expert” participants.
