Can anyone explain this phenomenon> It is quite painless and intermittent and occurs most nights (has for about 20 years). The best description I can give is that it is a silent explosion of energy at the back or crown of the head. It occurs just as I am falling asleep. Occasionally it occurs on waking. Sometimes it is a stronger and more focused charge of energy that seems to dart one side of the head to the other just above the ears. There used to be, sometimes, a flash of white light behind the eyes at the same time, but that hasn’t occurred for a long time. I suppose it is just energy that has been blocked somehow during the day and I’m thinking liver Qi stagnation / liver Yang / excess energy in the GB meridian but I have never seen this symptom described in this, or any, connection and would dearly love to know precisely what it means. Someone suggested it is Kundalini rising. I’d like to think so but, somehow, I don’t.
