Yeah, I forgot to mention the lines on both sides of head, to me, these lines are just above (about 1 cm) the highest point my ear that connects to my head. And on some occasions, it can move to other places but it mostly stays at the back of the head. And it moves independent of my will.
and one more thing: when I decide to send healing energy to someone else, a headache starts at the time I get finished, which becomes something feels just a bit more comfortable when I gather energy from my environment in return. (not people)
