Master Kim, thank you for your answer!
It is really interesting how all theese energies and fields communicate and influence on our body and mind.
But I think that the best way is to check it by own experience

When I asked this question I was thinking about changing place of my bed in the bedroom. So I decided just to try to sleep on
the West by my head for some time ( before I slept on the South). And I feel much better in the morning now
To be this experiment clear it would be great to try to sleep on the North and the East, but I think it will be difficult
May be some of visitors on this forum will tell about which side they sleep and how they feel?
