Hello doc, In afternoon after food I just kept 2 pillows and slept on one side right arm. In between sleep i just felt my body is dead and heavypressure in head, it something like blood cut off to brain, I just felt hard to move my body and suddenly I had taken long breath by waking up. It happened so many time when I slept on my neck. Is it anything wrong or it's due to cut off in blood circulation to head due to poor posture???
