Abstract (summary)

I have addressed two questions over the last ten years in my research program into lucid dreams: who is the individual who spontaneously experiences the lucid dream, that is, to find out if there is something unique about that person; and what is unique about the psychological experience of lucid sleep consciousness, beyond the awareness itself. I’m going to be talking about the latter today. Specifically, I’m going to be comparing sleep laboratory collected rapid eye movement (REM) lucid and nonlucid dreams. In these content analyses we used Hall and Van de Castle’s (1966) system of analysis of the manifest content of the dream, focusing on a count of the act frequencies. We basically counted the number of elements. This is a simple kind of conceptualization of the psychological content of dreams but one we have used in the past because it allows comparison to normative samples and can be simplified for computer entry of the data. With this first look at the content of these dream experiences we can compare the data to both the classical literature on the psychological content of dreams as well as to the previous content analyses of questionnaire and dream diary collected lucid versus nonlucid dreams (Gackenbach, 1988).
