I was meditating, or at least trying to, this morning. During the session (bear in mind that it has happened before) my head began to drop and I would have what I would describe as a very mild spasm, my head would jerk back. The same happened with my legs and feet, occasionally my feet would jolt. I was wondering, is this anything to do with the expansion of my energy body snapping back into it's usual place during waking state? Or is it something else?

Another strange experience I had was a sound that I would describe as someone brushing or pressing their hands over/on my ears and releasing them, to create a slight "pulsing", with large gaps in between each "pulse," as it were. I've no idea what this is caused by. Any suggestions?
