I don't know :-$

I don't like the feeling of it. It mainly happens when I'm most relaxed (although not in meditation) and pretty much only when I'm alone.

I used to think it was something interfering with my energy field, but now I wonder if it's energy trying to flow but hitting blockages and causing a jolt.

In meditation i get funny little cracks and clonks in my neck which is another strange thing as i'm not moving. This feels quite nice though!

Thank you
