If you are, you are just commenting on what google thinks. It is not hypnosis, and many people don't even know what hypnosis is.
hypnosis is programming macros, or adding things to them.
Side note, there are some techniques of putting people to sleep, although they are used most by passive viewing of anything. Most people that watch TV, are put to sleep, by the one way interaction.
If someone on tv says something you disagree with, you want to object, but most don't and that can train a passivity.
However same things was true with books before TV. Hence why so many 'thinkers of old, exchanged ideas in letters' they are more conversational.
If the comment is about manufactured sounds to program, that was done with disco where the 'sounds' that were most liked were computed then put into a form of music, and it crashed hard, so that does not work.
Some things like video games can have patterns that put people to sleep, there is a guitar hero video game you tube clip that had that effect on me, had to work to break out of the sleep just from watching the video with the pattern of music and moving images.
As far as sleep, if you can play tetris for hours, that is a better example of how that works, some established pattern, then the brain shuts down, and can be more receptive to ideas. Although you don't have to see the ideas the same way they are trying to be presented.
Do the hustle Great dancers in this video, and it does have a relaxing sound, but it does not program me.
