This morning I tried the energy session E03. 10 minutes and "full speed ahead". There in the process of listening frequency (at least carrier) is walking down up. So when she gets in the low frequencies, I have a "resonance" condition, when I feel like I shake from the body, strong tension, like a stretched string, the closed eyes start to move involuntarily (or strain) in sync with the light flashes... Feeling that something is about to happen...
I wanted to know:
First, as normal and than it can end?.... it's one thing if the astral

and the other if bleeding in the brain
Secondly, the question is rather to Andrei Patrushev, as a man certainly knows the structure of this session that it may be for the frequency and why is it such a reaction?
