Hey guys. This is very similar to what I'm doing if I experience a noisy or dream saturated mind. The main difference is that I repeat and modify everything that enters into my mind, not just mentation. Turning spontaneous mentation into suggestions then cutting the thoughstream off with silence is a great way to make yourself heard. But you should not neglect visual and auditory imaginary either.

You need to be very fluid and reflexive to catch all impressions, even the most subtle ones, that enter your mind. Think about it as losing your grip on the waking reality by turning inside and focusing on the confines of the changing content of your consciousness. The content will change but your focus remains firm on its confines. Like imagining that your follow a flying bird by having your point of view orbiting it and not looking at the ground or the sky.

If you get anything from this post get this: you need to strain for a state where you can watch yourself watching yourself. This will take you one step back further into your mind. You can do this with questions as well but that's another post. Instead, concentrate on the base of your neck and watch the content of your mind closely and passively, without being involved.

Then when you catch yourself drifting off in thought, repeat the last sentence slowly. If you repeat it a couple of times even more slowly you can turn off the internal dialogue. But now you want it to modify and turn into a positive suggestion. Then you can sort of swallow it down into your abdomen or get it behind you so you can be fully confident that it remains in effect working for you.

Similarly, if you hear a voice repeat what has been said then charge it with your goal. If you got a visual impression of an object take it into your hands and use palpation to help it visually recreate in your mind. Then go for a brief walk. You may need to put the object into a made up environment. But whenever it's possible use the environment that's given. Do dream specific things such as putting your hand through a wall or hover off the ground or tell to people around you that you are dreaming. Then reestablish silence, the neck focus and watch for the next wave. I've been doing this for more than 10 years.
