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.
Depending on who you ask (or which site you visit), a dream can last anywhere from a matter of seconds to 45 minutes. Dream Moods states people dream one to two hours per night, fitting in about four to seven dreams. Dreams last 5 to 9 seconds, and you have a dream cycle near the end of each 90-minute sleep cycle. You need a minimum of 4 dream cycles per night to remain healthy. Most of those dreams are called clearing dreams as we get rid of the emotional baggage and mind-clutter that accumlates thru the day while we dream.
