It can be described as the feeling or sensation that the body is spinning or that objects are spinning around it.
And kind of something similar is what we feel when we face (out of the blue) the unknown, when there is a no written path or rules to follow. So then, you hope you can find at least someone or something to hold on to so you can feel secure.
Sudden changes, moving away of what you control and enjoy can be scary. Listening, watching how people acts and what is going on around you, helps. And if you mix it with what your inner self tells you, everything gets better. And then, the spinning slows down, the vertigo turns into something different, a bit of nervousness as you feel the thrill, the challenge and the growth right in front of you.
