Patients with idiopathic REM Sleep Behavior Disorder (iRBD) and those with Non-Rapid Eye Movement Parasomnia (NREMP) differ not only in the content of their morning dream recalls but also in the structural organization of those recalls. iRBD patients were more likely to recall dreams and had more white dreams (feeling of having dreamt without memory). Speech graph analysis revealed that iRBD dream reports had stable, linear sequential structures, while NREMP dream reports were more recursive and less stable, with higher graph connectivity scores. These findings suggest distinct underlying mechanisms for dream recall in these two sleep disorders.
