Look into the Solfeggio frequencies, I've been using certain ones for different reasons. I came back from a sprained ankle and dislocated toe in 10 days by bombarding the affected area with 285 and 528 Hz frequencies with just a wireless Bluetooth speaker. The past few nights I've slept with 963hz playing and have had some interesting visions. 963 is supposed to be the God frequency, it opens the pineal gland. I've tried all 9 and my mind and body seem to operate more smoothly.

I'm working on a small chamber with speakers to see what it can do when focused.
