Lucid Dreaming | What brainwave entertainment to use?

Hello!
I hope this is the right place to post this :D

I read an article about brainwave entertainment (B.E.) and lucid dreaming. It seemed pretty good so I want to give it a try.
Basically, I want to know what kind of B.E. should I listen to BEFORE going to bed (This is when I meditate). Maybe you can give me a youtube link?
And then I want to know what kind of B.E. should I listen to before attempting WILD?

I am asking because there are many types of B.E.s on youtube(focus, lucid dreaming, sleep, luck etc) and I know that if I want to fall asleep fast should listen to DELTA or something and If I want to lucid dream then I would listen to a higher frequency..

I hope you get it and can help me :)

Is the usage of these correct?
