@UltimaDude your right it isn't the only type of trauma but that's usually the type of Trauma it takes for someone to awaken either the Sharingan or Byakugan. I think Himawari activating the Byakugan has more to do with her age than anything else. But I think Himawari awakening the Byakugan through Trauma is pretty much a confirmation that the Sharingan and Byakugan are awakened in a similar way.
