Hello, as soon as I start practicing your meditations, at night, at about 3 o'clock, I find myself in an unusual state. It's something like sleep paralysis, but it's not scary, it's even nice. At first, I feel white noise in my ears. It's like the sound of static on old Soviet televisions. And then the unusual feeling, as if weightlessness, is difficult to explain. What is it that meditation affects so much?
