I'm not talking about aggressive head banging or something, just sometimes while dancing I move my head to the side.

For example, sometimes I have a sudden movement in my head to the side while listening to a good song and feeling good from it (not even dancing). It's just the rush (probably from adrenaline) that sometimes causes my head to move a little bit uncontrollably very quickly.

I was talking about just moving the head to your sides a little bit, nothing continuous.

Is this sudden movement to the sides as dangerous as head banging? It happens to me occassionally while listening to music, and also while dancing it's not very aggressive - it's just once in a few minutes.

So does it damage my brain more and more every time I do that?
