Abstract
This report concerns Entoptic Rotating Spiral Waves as observed and documented by the author over a period of 46 years (1962-2008). The manifestations of these state-dependent, elusive rotating spiral entities were brief, emerging only during sleep-to-waking arousal epochs (in limbo). The images were seen only with closed lids in favorable ambient lighting-here, termed the umbral view. The clusters of rotating spiral entities emerge briefly to conscious view; their angular subtenses are estimated to be between 1° and 4°, and the rotations at ten-turns per second. Epochs of these activities commonly continued for about 20 s, with longevity of each visible entity up to 4 s. 90% of all observed entities were circular and outwardly levorotary; 5% were elliptical, appearing only as horizontal (prolate) entities. Overlapping units were rare, and were chiefly elliptical. Observations of twin spirals were also rare, seen in counter rotations, each twin inwardly rotating.
Highlights
The paper reports observations of subjective entoptic phenomena made by the author between the years of 1962 and 2008
Manifestations of entoptic rotating spiral waves, as observed and documented by the author when transitioning from sleep to waking, are detailed in this report
While 90% of all observed entities were circular and outwardly levorotary, rare inward spirals are observed
Summary
The paper reports observations of subjective entoptic phenomena made by the author between the years of 1962 and 2008. The entoptic rotating spirals observed emerged spontaneously, and were not provoked by the use of any pharmaceutical agents. These spiral waves have, in my experience, appeared only in the state-dependent condition of sleep-to-wake arousal. As the dark-adapted observer stirs from sleep, the rotating spirals that arise in the brain emerge briefly to conscious view if the eyes remain closed but illuminated: an umbral view
