Dizziness with Vagus Nerve eye gaze exercise… normal?

Hey guys I was told to do this exercise where you have your hands behind your head while laying down and look as far to the left and right as you can for 10-30 seconds and reset in the middle. It made me very dizzy during and have continued to be dizzy for hours later. Does this mean my nervous system is very disregulated? I am constantly in fight or flight and anxious daily. Is this another issue with something like craniocervical instability? Thank you 🙏
