Lambda waves are super fast triangular waves. They are in the range of 100-200Hz, and they happen on top of epsilon waves. They are associated with wholeness and integration of your whole being and the experiences you get daily out-of-body experiences, hyper-focus, and more.
As most people are living in beta and alpha, the field will take some time to speed up things. Using it with meditation, the field can show you other deeper levels that you haven’t seen until now.
Can this DM act like a booster for the integration of others fields ?
Yes.
Is there any real-life application for this frequency?
Has anyone tested it?
What does it give?
I’ve gotten interested, but I don’t understand if I need it or not.
At first I’ve read it like LambAda Brainwave 
This field is very interesting to me. I haven’t used it in a while, which honestly feels like a waste.
I’ve used it during meditation, especially in practices where there are things to see, explore, and change—something like Neoshamanica, or even astral viewing.
I don’t think there would necessarily be a very noticeable effect if someone used it without any particular purpose, although who knows—perhaps it could still produce some uncontrolled or unexpected states.
What changes for me during these visions is that everything starts becoming much more vivid and colorful, almost as if it were physically real, while at the same time everything seems to accelerate many times over.
You know that feeling when you exit a highway where you’ve been driving at 180 km/h and suddenly have to slow down to 40 km/h as you enter a city?
That’s what this field feels like, except in the opposite direction. The brain seems to accelerate so dramatically that time as we mortals normally experience it disappears, and you enter a completely different sense of time—perhaps something closer to the kind of time in which many extraterrestrial beings exist, where a single lifetime could span several million years, yet you are still able to act and process things incredibly quickly.
You know the 80/20 rule? The idea that only around 20% of our efforts actually produce most of the meaningful results in the world. When using Lambda and moving outside our normal perception of time and space, it feels almost reversed: a single effort can produce something like a 90% result, while simultaneously affecting several different areas instead of producing only the one specific effect you originally intended.
I hope I haven’t confused you even more now. 
P.S. I wouldn’t recommend using it when you’re tired, because it requires quite a lot of energy. Even though the field itself has energy built into it, the effect puts a lot of strain on the brain—it’s like suddenly shifting from first gear straight into fifth. It simply requires more from you.
Thank you
No, everything is very clear
I grasp concepts and abstractions perfectly
