Experienced intense physical sensations after Dzogchen transmission (Bon tradition). Looking for advice
Three years ago, I received a Dzogchen transmission during online classes with a teacher from the Yungdrung Bon tradition. Just to be clear, it was a long-term course, not a one-time session.
At the moment of transmission, I experienced a very strong, intense, and prolonged pressure in the center of my forehead.
At one point, I even got scared that it wouldn't stop.
After that, I started experiencing vibrations in my forehead area. At first, they were very strong; it felt like a hole was being drilled between my eyes. This sensation appeared constantly as soon as I relaxed, for example, right before sleep. It was highly intrusive. I would lie there trying to relax, and these vibrations would happen. When I was very tired, I would try to roll over on my side and fall asleep, but I ended up waking up from even stronger vibrations in my forehead.
Gradually, these vibrations began to change their character. I would say they became more like a movement in the forehead area; it's hard to describe in words. Generally, they occur not only in the forehead but also at the crown of my head.
I've noticed that they constantly intensify, but only to the extent that I can tolerate them. It's as if I get used to a certain level of intensity, and then they get stronger. This has been going on for 3 years now. They arise almost always when I am relaxing, and also whenever I experience any strong emotions.
I have tried asking teachers about this, and most of the answers came down to the suggestion that it is most likely a "wind disease" (rlung disorder in Tibetan medicine).
I don't have a personal mentor to whom I can ask this and get a detailed answer, so I want to try asking here.
Basically, what is this exactly?
If it is indeed a wind disease, how should I treat it? If left untreated, what will happen next?
I also understand that I probably need to meditate on space (sky gazing), spend more time outdoors in open areas, and do more physical exercises.
Has anyone here had a similar experience, and could you please share your insights?
