I had that same gallbladder dream again and I didn't sleep good. But I did finally find the piece of music I've been trying to find for years. Its actually from several SpongeBob episodes and its called Untuned. Its just music. Not any words. And only 25 seconds. I tried finding it in 2016 or so but the only google result that came up was some other guy looking for it too. So it helped me fall asleep the first time and it got me back to sleep at 4.
