Involuntary Muscle Movement and Possible Auditory Hallucination (?)

Hello

I have experienced sudden, involuntary head movement accompanied by hearing gibberish at two times the speed, following exercise.

It happened while I could feel my blood pulsing strongly (I'm guessing this is because of increased blood pressure).

It didn't last more than -at most- two seconds.
Also, I didn't experience anything quite like this until now.

I'm concerned about this and not entirely sure whether or not I should go to my doctor for such a minor thing.

I know it sounds weird, and compared to other posts here, a bit unprofessional. So I apologize in advance.
