Question: There have been many studies on the topic of dreams in the world. Sleep is a state when man’s contact with the outside world slows down and there is some kind of brain reboot, that is, the conscious activity stops.
What happens to a person who is in attainment of the upper world? What is the state of “sleep” for him?
Answer: Sleep is the lowering of a person from the full GAR degree to half of this degree—VAK. This state of semi-attainment is called sleep.
It has nothing to do with physiology, neither with wakefulness nor with sleep on the earthly level.
