You can get very good at lucid dreaming with practise. In high school, when I had plenty of time to sleep all day, I practised it a lot. It's a fun thing to do but getting really good at it can take a long time.
I still go lucid fairly often though. Once you get used to realising that you're dreaming it will happen regularly. Often when I get the beginnings of nightmares I can get rid of them by realising I'm asleep and change the dream.
It can be a lot of fun too and incredibly realistic. If you want to get into it I highly recommend this book: http://www.amazon.com/Exploring-World-Dr...705&sr=1-1
