Hello, I have joined this forum due to this lingering problem. I have been doing meditation for quite some time and now i find this strange problem. When i sleep with face seeing up, the back side of my head gets exceedingly heavy and it seems like the heavy energy is pounding in my head. Moreover, i get up late in night and feel extremely fearsome. I don't know why but too much fear from nothing. The heart seems to palpitate and then i sit up and actually request the energy to move down. I feel ok when the energy moves down. But this happens every night and gets aggravated when i am more actively sexually. For this reason i am totally abstaining from being sexually aroused at any point of time. But this is happening every day. What's the solution? Can anyone advise?
