A fun thing that helps lucid dreaming is to practise jumping in your daily life. Get in the habit. Randomly jump. At work. Queuing for the movies. At a party.
This habit will cross over to your dreamworld. Then, when you jump in your dream, you come down much more slowly, so you know you are dreaming. (If you are not dreaming, you come down quickly.)
I have used this method to successfully launch many wonderful lucid dreams. A bonus is that once you realise you are coming down so slowly, it is very easy not to come down at all.. ie to fly!
