When you are awake with clear consciousness, your brain is in the Beta Wave State. The brain's beta waves have a frequency of 14 - 30 oscillations per second
Your brain is in the Alpha Wave State, when you are relaxed but not sleeping. The brain's alpha waves have a frequency of 9 - 13 oscillations per second
In the several states of lower consciousness, while sleeping and dreaming or meditating, the brain oscillates at 4 - 8 Hz
In very deep dreamless sleep, your brain's delta waves have a frequency of below 4 oscillations per second
The sleeping program slowly decreases the frequency of pulses until it reaches a level of deep sleep.
Beside the sleeping program there are many more. You can see their different phases of electro magnetic pulse frequency and adjust them if needed
