I have sleeping issues and tried this. Need some post-listening advice and opinion. My listening as per video recommendation experienced the following :

1. In vortex spinning mode and shaking to and fro for a few seconds in Alpha phase (1st stage) and nearing Theta phase.

2. Upon entering Theta stage (2nd stage) there was like a loud “sonic boom” in my mind, felt thrusted forward real fast and I start to sleep, but not in deep sleep.

3. Woke up a few minutes after video ended with body ache and aching joints, have a good bath and aching gone but tired as if after playing physical sports.

Input and advice appreciated, should I do this again next day?
Sounds like you experienced some powerful stuff! I might cut back by using one of the power nap tracks (in the afternoon) once a day instead... https://youtu.be/r_nOgNmhgc4
After a couple weeks, come back and try this sleep track (at night) again.
