Dreams remain a poorly understood aspect of human life. Traditional methods for analyzing dream content rely on over 130 rating scales and are limited by small samples and retrospective surveys. To address these limitations, researchers used natural language processing to identify topics in 44,213 dream reports from Reddit's r/Dreams subreddit. The analysis uncovered 217 topics grouped into 22 broader themes—the largest collection of dream topics to date. The topics were validated against the established Hall and van de Castle scale.
