For both groups, Indentifying subscale correlated positively Nightmare Distress scale Questionnaire. Conclusions: Elevated idiopathic rapid eye movement patients, especially difficulty identifying feelings, parallels evidence dysautonomia The incidence distressing nightmares association further extend similar findings clinical non-clinical samples suggest an affect regulation disturbance may be common sets symptoms.
