By Sharmain Cornette. âAbout two percent of the patients who undergo open-heart surgery worldwide end up with a stroke.â This notion was amplified yesterday by Chief Executive Officer of the Caribbean Heart Institute (CHI), Dr Gary Stephens, during an interview with this newspaper.
Dreams mainly occur in the rapid-eye movement (REM) stage of sleepâwhen brain activity is high and resembles that of being awake. REM sleep is revealed by continuous movements of the eyes during sleep. At times, dreams may occur during other stages of sleep. However, these dreams tend to be much less vivid or memorable. The length of a dream can vary; they may last for a few seconds, or approximately 20â30 minutes.
Enuresis, Somnambulism, and Nightmares Occur in Confusional States of Arousal, not in âDreaming Sleep.â. The result of the study âSleep Disorders of Arousal,â by Roger J. Broughton, shows the differences in normal sleep patterns and those of a bedwetter. In normal sleep, people fall slowly from Stage 1 (lightest sleep) into deeper stages, and then back to lighter stages, where itÊ¼s easy to awaken. A bedwetter falls quickly into deep sleep and stays there for longer periods.
