First you should determine whether you're experiencing a forceful normal beat or having actual abnormal heart rhythm during those symptoms. lying on your left side often makes the heart beat seem quite forceful. Some people when half awake and half asleep do get jolts of muscular activity which can excite the heart rate. I recommend wearing a heart monitor to record heart activity during symptoms
