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.
Your body is more or less paralysed, but your eyes move rapidly. Interestingly enough, while your brain waves frequency is much higher than it was when you were in the deep sleep phase, it's even harder to wake you up. After some time in the dreaming REM phase you fall back into deeper sleep and the cycle repeats. Usually each cycle takes about 90 minutes. When the alarm clock wakes us up suddenly from deep sleep or interrupts the REM phase, our body doesn't appreciate it.
