I tried AlexK's suggest to move that energy to the back of my head where the tangerine is. I can feel there was something really at the top back of my head. I somehow felf the same sensation when I am praticing Tai Chi (only a certain stance) that the back of my head is popping in beats and everytime I breath I felt there is an opening at the top back of my head. Now this I can't have control over it.
