I am a precog medical intuitive. A waste of a gift in our society, but there it is. LOL Anywho, I can hold my hands over people, close my eyes, and I begin to see colors and faces. It scared the begeezuz outta me when I first started doing this, but now that I understand what it is, no big. I kind of think this is what others have seen long before I came along, and what is referred to as being posessed or having the devil or a demon in you. It ain't that at all.
The faces that appear sometimes have teeth, one of them even looks like a werewolf (ish) kind of thing. Depending on the face and the teeth I see, I can tell if I am going over an old injury or something is wrong with that area of the body. I can also see faces that indicate emotional issues. Along with these I see a body at times when I think of another and what looks like electrical connections or something, usually starting at the head area and it lights up going through the body. Weird, but it happens.
I also see a specific face, and I call it the sign of a healer. I can see it my palms and the only other person I've seen this face in is a doctor, who doesn't really believe in psychic stuff enough to discover more, but knows and has seen enough to understand, something ain't quite right in China town. LOL If he only knew...it's twue! It's twue! LOL
Anyway, questions about these faces: If anyone else can "CT scan" others, do you kind of tag the faces and associate them with specific things. Curious if mine are different than others or not. I looked for symbolism of healers, but had no luck finding this. Would love to swap a picture I drew of the healer face I see, with someone else who sees as I do. Just to know if those of us who see these things all see them in the same language or something. I sort of think of these faces and teeth as a new language I'm learning. And no... They are not devils or demons, just signs that something is amiss within and must be dealt with. No exorcism necessary, thank you. LOL
Sometimes I can see an animal this can be signs of cleansing or a shadow requiring healing. It depends how it unfolds.
Some of what you are speaking about is resetting the circuits and rewiring. That all sounds like healing.
What these exercises have done is open my 3rd eye to see energy and face masks of 2 other people During the day.
As to what you describe at the head there is a belief that the center hot spot of sorts is in he head. The lower back can be inherited stuff. This is a belief of some indigenous people.
You might want to make notes of your dreams. As it sounds you may or will move into that area during the dream state.
