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.
If you dream it means you're in REM sleep, but it is uncertain how important REM sleep really is. Also just because you can't remember dreaming doesn't mean that you don't actually dream. Dreaming and believe it or not, nightmares means that you have entered REM sleep (rapid eye movement) which is excellent sleep. A lot of sleep studies have proved this. Experts say that REM sleep starts approximately 1 and a 1/2 to 2 and half hours after you knock out, unless it was a drug induced sleep.
