That would be non-volitional neurotherapy since you are not doing anything to cause the change. Do you have ear phones on or does she say if she is making any inputs ?

It does not sound impressive to me. If it was benefiting you, the chaos would start to decrease. Does she say anything about whether the level of chaos is decreasing ?

It sounds more like she is using it as a relaxation device. That is not uncommon. In fact, they usually get FDA approval to only promote it as a relaxation device.

The usual goal is to teach you how to cause your brain to go into the calm mode without the device. Sounds like a 'guard your wallet' situation to me.
