Focus 10: feeling energy move

I started focus 10 for the first time today at 4 in the afternoon. I was feeling drowsy and wanted a nap but wanted to do this. As he started counting down it was almost as if it was true how my mind was wide awake (despite me having been very sleepy) but my body was very, very still…. Then I began to feel around my hands waves of energy that are flowing, almost like the waves of energy had some invisible mass that was moving around in a synchronized pattern….

Also I am an avid meditator and the last time I have felt something like this was when I was deep in my training in Ganapati Meditation
