Abstract
Oneiric Stupor (OS) in Agrypnia Excitata represents a peculiar condition characterized by the recurrence of stereotyped gestures such as mimicking daily-life activities associated with the reporting of a dream mentation consisting in a single oneiric scene. It arises in the context of a completely disorganized sleep structure lacking any physiological cyclic organization, thus, going beyond the concept of abnormal dream. However, a proper differential diagnosis of OS, in the complex world of the “disorders of dreaming” can become quite challenging. The aim of this review is to provide useful clinical and videopolygraphic data on OS to differentiate it from other dreaming disorders. Each entity will be clinically evaluated among the areas of dream mentation and abnormal sleep behaviors and its polygraphic features will be analyzed and distinguished from OS.
Highlights
As the search for an understanding of dreaming is more than thousands of years old, scientific evidence developed over the last century [1, 2]
Dream ideation of Rapid Eye Movement (REM) sleep intruding into wakefulness gives hypnopompic hallucinations a greater emotional load, as unpleasant and frightening experiences, especially when associated with sleep paralysis, where the muscular atonia at EMG extends into wakefulness [85, 104]
Studying 45 adult Disorders of Arousal (DoA) patients we found that 35 patients (77%) reported that, even if not constantly, they could recall some kind of mental activity at the end of the episode
