the simple three tricks I use to help lucid dreaming are
1. Pushing my index finger in the palm of my other hand during the day, in a dream your brain fails to emulate this task properly and you'll push your index finger right trough where you think your hand is supposed to be.
2. Writing down dreams in as much detail as possible. Just meditate and think of nothing but your dream and push yourself for details you think you cannot possibly remember, because you can remember them.
3. Consistent sleep schedule and try to get in touch with when you enter deep sleep, rem sleep or when you wake up. The more awareness in those 8 hours, the more controll you can exercise. meditate and write them down.

carefull of snakeoil, theres alot of pseudo science out there as the concept itself doesn't lend itself to be very scientific.
Sounds like a stretch to label this as a success. What are the chances that a "correct" response was randomly encountered?
