Maybe Alfred Hitchcock could explain it better as he came up with the term vertigo

 

[Johnney Herbz]

Your brain is being deprived of oxygen and the blood rushing to your head.

Agreed i believe that it is lack of oxygen

It also occurs when your blood pressure drops.

Dehydration, lack of oxygen, blood pressure, blood sugar.. few things could be goin on
