I’ll tell it straight: I am not a big fan of dreams, the science behind it or know about dreams beyond what I’ve been taught in introductory psychology. I’ll just it post here to say that even dream researchers have thought of looking at video games. No I haven’t read the article (just the abstract) because it would be way over my head to review it with my lack of knowledge in that field. That is all.
Revonsuo proposes an evolutionary theory of dreaming in which dreams allow an individual to prepare for real world threats in the safety of the virtual setting of the dream world. Based upon previous work examining the dreams of video game players, it was hypothesized that high-end gamers would experience fewer threat simulation dreams because of frequent threat resolution rehearsal during game play. Subjects were asked to report a night before dream and fill out surveys regarding their gaming history, media use, and dream experiences. Using a factor analysis, support for the main hypothesis was found. Individuals with a history of game play experienced fewer threat severity variables in their dreams.
Apparently, there’s a previous study by the same first author that was published in 2006.
