Lucid dreaming is something that will get easier and more consistent the more you practice it. To encourage it, try "reality checks" in your waking world. For example, consider that in the dreamscape written words and numbers never -ever- make sense. So find something written on a sign or on a wall...something stationary...and visualize it moving and shifting as if it were in a dream. Or you could preform "am I dreaming?" checks, where you look for similar clues as to whether or not you're asleep. The most popular technique is to wear a wrist band or write on the back of your hand something simple, like "Not Dreaming". Don't make it a whole sentence or ti takes too long to check. If you have the phrase, and you can read it properly, you're awake. If it doesn't look right, you're dreaming. Check it periodically through the day, and tell yourself that when you begin to dream you'll check it as well, and eventually it will become habitual and you'll actually do it in your dream. This gives you a prime opportunity to gain lucidity with a simple trigger.
