Hello MK! A popular starting-technique is the Dream Induced Lucid Dream. You can look it up in the tutorials section for more details, but basically it is getting in the habbit of doing "Reality Checks" (Tests which should succeed in real-life but fail in a dream telling you it is a dream) and recognising dream-signs. This technique is nice because you never have to wake up, and it is actually prety easy. The downer is that it is unpredictable so you can't really plan WHEN to have a lucid dream, as they happen randomly.

Whatever you choose, good luck!
