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.
Dreams are basically stories and images our mind creates while we sleep. Dreams can be vivid. They can make you feel happy, sad, or scared. And they may seem confusing or perfectly rational. Dreams can occur anytime during sleep. But most vivid dreams occur during deep, REM (rapid eye movement) sleep, when the brain is most active.
