The soundtrack to the film Waking Life is really good, and the film is about lucid dreams, so I associate the music to lucid dreams. Do you think it would be beneficial to play this music softly as I perform a WBTB technique?
If you are associating the music with lucid dreaming, then yes, it will be effective.
I just finished trying my first WBTB technique. This is my first attempt at a lucid dream, since about a year and a half ago, when I wasn’t vey successful. Anyway, it hadn’t seemed to work, as I don’t think I was tired enough, I kept on waking up. Then I drifted back to sleep, and then had a sensation of wind rushing in my ears, quite unpleasant, and then I looked at my digital clock and the numbers were all mixed up. I at this point, I obviously knew I was dreaming and became lucid. I tried to keep calm and I think I did, but I woke up! Infuriating. 
But now I feel that what happened wasn’t actually real, and was perhaps a hallucination based on my desire for lucidity. Is it possible to have a dream where you think you became lucid but you didn’t? Perhaps this sensation is just a result of the dream memory eraser in my brain. All very exciting anyway.
Looking back on it, could this have been a WILD rather than the DILD I thought it was? Because, it seemed as if I was lucid from the very start and the dream sign was just a confirmation of what I already thought. I’m confused. Could someone tell me what happened and why I woke up. I kept calm, but should I have actively willed the LD to continue?
Im not an expert, nor am i bright, but sounds like a bit of both, the wind rushing through your ears could have been the sounds you hear while passing through the barrier… so to speak and the fact that you did a RC… idk it sounds like it was a dream induced… but you need to ask yourself did you fully go through a wild? did you … feel yourself passing through the void into your dream. or was it sudden and you were in the dream and realized it, its very confusing… something you have to figure out… but hey you did it, so who cares
