Signal diversity (back transformed from identity link gamma GLMM for 1–SD) as a function of sleep stage, experience class and thought-perceptual rating of dreams.

^aThe CI for the between-participant variance in this model was gigantic, indicating possible problems with model fitting. Excluding/winsorizing the smallest one/two LZC values lead to plausible CI, and gave otherwise similar results, as did a beta GLMM with logit link (Supplementary Material). NE, no experience; DEWR, dream experience without recall; DE, dream experience.
