The sleep cycle is repeated many times throughout the night. Each sleep cycle lasts 90 minutes, usually it takes about 30 minutes to enter dreamland. Therefore, a lucid dream can last up to one hour. After that, the sleep cycle will restart again.
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.
