Examines links between synesthesia and lucid dreaming, indicating ways they may enhance each other.

The research aims to explore the connection between synesthesia and lucid dreaming through perceptual presence and counterfactual-richness.
Surveys conducted with 616 adults using a synesthesia self-report and the LuCiD scale.
Cluster analysis identified four synesthesia subtypes.
Regression analyses determined type-specific effects on elements of lucid dreaming.
Personality traits were assessed using the Big-5 inventory.
Perceptual synesthetes reported more frequent lucid dreams and better control over them.
Negative interactions between conceptual synesthesia and personality traits like Openness and Extraversion diminished dream experiences.
Findings highlight qualitative differences within synesthetic experiences that relate to dreaming.

Matsuda et al. (2026) studied this question.
