Cool idea. I used to experiment with bineural beats and psychedelic rock to change my dreams. It turned me into a lucid dreamer so it kinda worked.
Would be interesting to see what could accomplished with a bit of applied science.

I have this thing where if I hear a tv show or movie in the background while I am trying to sleep I will dream the show/movie into my dreams.
Like one time when I was a teen I remember I was watching a marathon of the tv show Charmed (Original not the one that recently came out lol it was like 1990s lol)
I ended up dreaming I was a witch as well and I was a friend of theirs.
Lol my husband likes to mess with me if he wakes up first. He play endless videos of Jack ass and I always end up as either the buzz kill calling the guys idiots for doing stupid shit or the worse of them by saying how they can make it even more wrong lol

From experience, the sounds from the outside world does have an impact on my dreams (the birds were chirping and I ran into crazy, loud barking dogs in my dream, same sounds for some reason)
It has happened countless times.
But I'm not sure it will work on a deeper level.
Dreams have always been an interesting yet hazel topic due to difficulties in researching and studying.

I listen to music every night when I go to sleep- sometimes it’s Muppets and I have really wild dreams XD

Muppets? Like the sock puppets you play with your hands?

More like Jim Henson’ puppets ;) You’re thinking of sock puppets

First I listened to the Pentatonix Christmas Album, then I had a Dragon’s Egg Bath Bomb from LUSH. Now I’m reading my random illustrated facts book :)

Starting Season 1 of Foster’s Home For Imaginary Friends on AppleTV :)

That's a lot of things
How is the bath bomb btw, I've never used one but it's so pretty in the picture

Is it healty to sleep to music??

...Toilet Time...Lol

I’m quite healthy and I’ve been doing it for years
Bath bombs are nice but there’s soap in them so don’t put your head underwater

Ok ok look i want details... like do you leave earbuds in your ear??? Or what?? I am confused here

I put the radio on and listen- no earbuds- not sure where you’d get that idea

Hmmmmmmmmmmmmmmmm
