Yeah, sorry for not highlighting the subjectivity of the experience. Tbh, I also had moments in which the dream is not as full res as real life.

In Advaita vedanta there are 4 states of existence of self. First is the outer world where there is a concept ok others and physical world. This is the world is beyond our control. There is suffering in this world. Next is the dream state where we can control everything. This is illuminated by our own mind. Even then there is limits of what we can do. Continuous lucid dreaming gives us fatigue for those experiences.…

I suspect, but don't know for sure, that most people remain (barely) conscious during dreamless sleep, or at least parts of it. However, we don't remember it as sleep. When we are awaken in the middle of dreamless sleep we simply believe we were lost in our internal monologue.

This is most apparent when somebody is taking a nap, possibly even snoring, and when awakened they believe they were not sleeping at all.

Now, in most people, this dreamless sleep isn't a quiet, sharp, blissful experience, but rather a blurry incoherent mess of internal monologue.

If you practice falling asleep consciously, you will find your internal monologue progressively become more and more incoherent and disjointed, until a point when (REM) dreams manifest "out of thin air". This is easiest done as you approach your usual waking time, what in lucid dreaming circles is called WILD.

That is my personal experience, anyway.

I also believe that experienced meditators go through dreamless sleep with far less chatter and are able to maintain a sharp vivid blissful experience through the night.

Usually the term "non-invasive" in a medical context means they don't need to cut you open to do something; not that an intervention doesn't do something.

Fair enough, yes. That said, people need to understand that this (as I understand it from the article) is absolutely having a physical tissue-level effect on their brains, and it's not necessarily a good thing.

Completely agree, ultrasonic cavitation presents real and significant risks.

While I'm happy there's more R&D going on in this field, I'm highly skeptical about the use of TcU -- people move around to much while sleeping for this approach to be effective or safe... and there are less invasive ways to accomplish this.

One of my projects is a dreaming machine which combines eeg, sounds, and lights to aid in recognition of dream states. The eeg data is used to generate ambient soundscapes that change theme based on the level of sleep (awake/rem/light/deep) and during rem sleep it triggers a set of leds mounted inside of my sleep mask. It works fairly well and is totally passive/non-invasive.
