Hey guys, just had a quick question for anyone with WILD experience

So, when I'm trying to WILD, could I theoretically play some soothing music/isochronic tones etc. on my phone or maybe even through headphones, and use that to hold my awareness? I feel like it would make it easier to stay focused but I'm not sure if it would make me 'too' focused and not able to fall asleep. Also, let's say I did use the music to successfully transition - would I just be hearing the music in my dream? Or once you're asleep does your body kind of block outside noise in a way? I'm wondering if that is true because if so it would make it way easier to know once you have fallen asleep; once you no longer hear the music you know you're asleep.

But I don't know, I've never tried this before so I just wanted to see if anyone had any experience with it or any tips/information. Thanks for your time guys
