It could be for anything, something you used to fall asleep, alter your body temperature, induce amnesia, etc, so long as it follows the criteria listed below.

I am only looking for hypnosis audios that fit the following criteria:
[1.] Are NOT "subliminal", are simply audible hypnosis scripts (no inaudible background suggestions/speech).
[2.] Are NOT sexual, must be completely SFW (Safe For Work).
[3.] Have obvious effects that you can experience and observe (easy to confirm it works as the effects are obvious and undeniable).
[4.] Have been "successfully used" (it actually worked) by the people recommending it (YOU).

Please post the specific hypnosis audio info:
- Creator/company name
- Audio/video name
- What it does (what effect / phenomena it causes)
- How effective it was at yielding the intended effect / phenomena (your experience)
- OPTIONAL - Any other details you think may be relevant

Thank you for any recommendations.
