Resumen
"During sleep, humans experience offline visual content that we call dreams, which are typically emotional and lack rational judgment about their strangeness. However, during lucid dreaming (LD), subjects know they are dreaming and can control the dream content. Another type of awere dream experience is the out-of-body experience (OBE) initiated from sleep paralysis. Although the differences between non-LD, LD and OBEs are evident, there is no record in the literature of such differences in dream content and some researchers describe OBEs as a type of LD. We conducted interviews with subjects who experienced LD and subjects who had OBEs frequently. A portion of them kept a dream journal for two months with precise instructions on how to write down their dreams. The collected dreams were analyzed by automatic methods of analysis of emotions such as EmoLex and Sentisense, also with classifiers such as Empath. The dream stories provided by the participants were scored with a series of ratings using a method based on Hall and Van de Castle's dream content scoring system upon which we developed variations and additional measures to adapt to the requirements of our task. The scoring was divided into sections, hought/emotion/action, presence of entities/characters and social interactions, sensory descriptions, spatial references, fantasy content, among others. Here we present the preliminary progress of this study of oneiric content."
