Use of dream phenomena within the debate between internalists and externalists is considered. In the first section, internalist and externalist camps are described, and conceptual tools are introduced to clarify aspects of disagreements between the two. The next section discusses the scope of externalist claims and whether they have a burden of proof to explain dream phenomena. Section 3 introduces what I call the standard conception of dreaming. An argument from standard conception against embodied views of perception and perceptual experience is raised in section 4. A potential confusion regarding the phenomena to be explained is highlighted in section 5, and empirical research questions pertaining to the debate are identified in section 6.
