Dream recall, alexithymia and depression.
Bibliographic record
Abstract
The issue of a quantitative and qualitative impoverishment of dream mentation in alexithymic subjects has been shown and explained as a general \ndifficulty of alexithymics in recalling their dreams [1]. On the other hand, this relationship disappears when the contribution of depression is \nconsidered (unpublished data). Hence, a multivariate design on a larger sample size has been carried out taking into account both alexithymia and \ndepression as predictors of oneiric experience. A sample of 443 undergraduate students filled-in the Toronto Alexithymia Scale (TAS-20) and the \nCES-D (Center for Epidemiological Study Depression) scale. Then, 144 of them (mean age 23.13 ± 2.72; 22 M, 122 F) accepted to audio-record \ntheir dream reports for 14 consecutive days. The transcriptions of their dreams were considered with regard to their length and emotional content. \nSelf-rates obtained by a dream diary were also considered to assess dream recall frequency, and their emotional valence, vividness and bizarreness. \nResults on dream diary measures indicated that the number of dreams and bizarreness were positively related to the CES-D scores, while vividness \nof dreams was negatively related to the TAS-20 scores. Analyses of dream report trascriptions indicated a coherent picture, with a positive relation \nbetween the depression scores and, respectively, the number and the lenght of dreams (as expressed by the Total Word Count), while a negative \nrelation was found with emotional valence. The present results suggest that different subjective and objective features of sleep mentation are \ncorrelated to depression or alexithymia. Hence, these constructs, although highly inter-correlated, keep an independent capability to explain \ndifferent sleep mentation features. On the other hand, the issue of a dreaming impoverishment in alexithymia needs to be reconsidered, since all the \nquantitative measures correlate only with the depression scores. Different quantitative and qualitative features of dreaming are related to \ndepression or alexithymia.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
