Hello, lately i noticed that after dancing at home and making swift movements with my head, the next day in the waking up stage after sleep i get nonsensical thoughts, so to say. my brain is very sensitive to any kind of sudden movement?

Not sure exactly what you mean by nonsensical thoughts. It does not seem like swift head movements would affect your thinking ability although it may result in neck discomfort and perhaps headache. If you could be clearer in your description and ask a specific question, we would be happy to answer with additional info. Hope this helps. Good luck!
