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.
:) What you experienced is quite normal for beginners. The dreams usually don't last very long for them once they become lucid, usually because they either get too excited, don't stabilize the dream, or try to do too many things or pretty advanced things right away. You have to try and stay calm. If you get too excited, you pretty much immediately wake yourself up.
