Exploring the link between synesthesia and lucid dreaming through perceptual presence.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study investigates links between synesthesia and lucid dreaming via perceptual presence and counterfactual-richness (abundant possible sensorimotor contingencies). We hypothesized that synesthetes would report more frequent lucid dreams because enhanced counterfactual-richness facilitates dream control and clarity. We surveyed 616 adults using a synesthesia self-report, the Lucidity and Consciousness in Dreams scale (LuCiD), and the Big-5 inventory (TIPI-J). Cluster analysis validated four synesthesia subtypes- Language-Color, Ordinal Linguistic Personification (OLP), Spatial Sequence, and Visualized sensation-consistent with prior work. Regression analyses revealed type-specific effects on lucid dreaming: perceptual synesthesia (Visualized sensation, Spatial Sequence) robustly promoted lucid-dream facets-especially control, and also insight, dissociation, and positive emotion-whereas conceptual synesthesia (Language-Color, OLP) showed negative interactions with Openness and Extraversion, thereby attenuating lucid-dream experiences. Personality analyses further confirmed positive associations between lucid dreaming and Openness and Extraversion, aligning with previous literature. We interpret perceptual synesthesia as an expression of excessive counterfactual-richness that enhances perceptual presence and sensorimotor contingencies during dreaming. These findings both clarify qualitative differences within synesthetic experience and suggest a new direction for understanding synesthesia and lucid dreaming as interconnected cognitive phenomena.
