1. It's most likely a lie. I am not saying that to start a flame war, I just have actual experience with this. As in years of dedicated experience.
2. Keep a dream journal.
3. Do reality checking throughout the day.
4. Meditate before sleep. Do a relaxation exercise. There's 100s of them.
"Lucid Dreaming: A Concise Guide to Awakening in Your Dreams and in Your Life" is the definitive book on the topic that everyone copies. No one has additional information.
What about it is most likely a lie? I've had dreams go lucid. I mainly want to use them to practice physical skills in the dream world and have them transfer to real life. I remember ready a study about it.
Not sure why he said that it's a lie. I have had lucid and vivid dreams that felt very real. The most significant one was when I "woke up" but in a dream. I then woke up again but this time for real. It was so surreal and at first I wasn't sure whether I was actually awake or still in a dream...
It haunted me for some time after because I never expected something like in the movie inception to be possible in real life.
A study to test this would be simple - test skills level at something (e.g. chess), and then have the study participant study "in their sleep" for a month. Test again. It has never been done. Not even close. As it has never been done, I strongly believe you are misinterpreting / over-stating your results.
