Sleep

To understand this unsolved mystery, transcends ability to grasp its scope, involving more than simple inquiry of mental test or scientific grope. Most nights you are a force I can't resist, when day's fatigue exceeds what one can bear, like being stuck in fog or hazy mist, where only you can rescue and repair. Infrequently you hesitate, elude, withholding needed dormancy and rest, perhaps because of apnea or mood, ignoring me and leaving me distressed. Regardless of conditions, day or night, your salve keeps my circadian aright.
