This is a really weird question.?

Question

Sometimes, when I'm sitting on my bed and my legs are crossed, I'll put my hand onto my chin, you know? And I'll be doing something like looking at my laptop screen, and before I realize it, my upper body is rocking back and forth unconsciously and I'm not even trying to do that.

Why do I do that? Do you ever do it? What does it mean?

Does anyone know what I'm talking about? Do you need additional information?

Answer 1

I have been sitting for a while in a meditative state and my body does that.  I expect it has something to do with meditating.

Answer 2

that is nothing more than the force of your own heart beat.
