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.
The sleep cycle repeats 4-6 times a night. We don't necessarily always progress through the sleep stages in a linear fashion. If your sleep is normal, you may reach your first REMcycle 60 to 90 minutes after you fall asleep, having gone from stage 1 to 2 to Delta to REM. This Delta may last 10 to 15 minutes and this REM may be very short.
