Dizziness and nausea is frequently caused by unusual physical motion (or perceived motion) - e.g. air sickness, sea sickness, car sickness, VR simulation sickness etc etc.

There are three commonly-documented versions :

* Caused by motion that is felt but not seen
i.e. sickness caused by the movement of sea air and land travel - except that it's experienced after the individual returns to the stability of dry land.
