Not exactly sure whether you meant it but here's the thing: energies rise up with meditation/pranayama. These give you sensations in different parts of the body most notably in your eyebrow/forehead/etc. Experiences like Hollow, digging, pricking, massaging etc.. I've not just experienced profound sensations, but I live with them. In every session I experience them daily. IN fact, I'm experiencing them right this moment while typing, in my forehead, a deep, hollow like sensation, as if some energies are digging some hole in the forehead. This is not painful or discomforting.
