Since I have been dabbling in OBE and raising energy, etc. I have, almost constantly, a sensation of tickling type across my forehead at the hairline. Starting at my widow's peak around to above my temples at times. mainly about 4-6 inches in length at the center. I had a chakra clearing, and actually felt release in the two areas he told me afterwards that he found to be dirty. This solidified my believe in the energy body and the metaphysical. But, it only pronounced this sensation. After the clearing, I went to a Reiki circle, where the owner of the establishment, and a master, was the one who gave me directly healing energy. Still this sensation is evident, even while writing this. I am in very good physical health at 6 foot 4 235 pounds, with a slim waist and muscular build due to exercise. I don't think this is a physical problem. Any ideas??
