I had the most excruciating headache today, couldn't quite figure where it came from, but after taking 1/2 of a pain killer (you know it would have to be a bad headache as I don't take any medication at all), I resorted to Reiki and prayer. I realized after a bit that I had been absorbing all sorts of foreign energies from physical people as well as spirit communication, but the sounds way too loud and muffled to decipher and separate. I cleared all of my chakras by connecting them to my clearing vacuum and remembered and old trick that one of my guides showed me for healing a headache. Close your eyes and take about 4 deep breaths, inhale the air into your tummy and fill it up making your stomach expand, hold it in for 4 seconds and release all of the air, when you have done this 4 times focus on your third eye chakra, clear it out by placing a clear bag/rose in front of it and allow any energy, images, sounds etc. to be released and fill the rose/bag. Once  cleared focus on closing the chakra completely. This is an instant fix!
