Alexithymia and Impoverished Dream Content: Evidence From Rapid Eye Movement Sleep Awakenings
Bibliographic record
Abstract
OBJECTIVE: Despite the repeated suggestion in the literature of an association between impoverished dream processes and alexithymia, little systematic research has been conducted. METHODS: Eight nonclinical adults scoring in the alexithymia range and eight nonclinical adults scoring in the nonalexithymia range on a measure of alexithymia were awakened for dream reports during their second, third, and fourth rapid eye movement periods on the second of two consecutive polygraphically monitored nights in a sleep laboratory. RESULTS: The alexithymic and nonalexithymic groups did not differ in the number of dreams reported or the number of words used in the description of their dreams. The two groups also did not differ in their self-reports of the emotional valence associated with their dream experiences. In contrast, the dream reports of the alexithymic group were rated as less fantastic than the dream reports of the nonalexithymic group. CONCLUSIONS: These findings provide additional evidence that alexithymia involves restricted imaginative processes.

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.
