Hey

1: When WILD'ing, you need to basicly get up and do something and then go back to sleep and try to enter a dream. If you wake up and don't move and try to dream, it's called a DEILD. DEILD is far easier than WILD and I wouldn't bother with a single non-lucid dream if you want to achieve lucidity. Sometimes when chaining DEILD's, you have to risk losing some previous dreams.

2: The goal is to relax enough so that you fall asleep. Binaural beats are supposed to change the frequency of your brainwaves or something like that. Mimicking the same wavelengths we have during REM sleep. Try to have them on low volume and go on about your business.

I also suggest you try the DILD technique out. Even though you might not want to rely on it to get lucid primarly, it's a great technique to get your enthusiasm up and score a few random lucids during the night.

If you've got any more questions, don't hesitate to ask
