Handstands and layback spins

I used to be fine doing layback spins and just feeling dizzy the same way like every single other spin. But when I started to do handstands like every day, every single time I do a layback, Im like so much dizzier than before and once even passed out when stepping out into my landing and having like really blurry vision after one today and i felt like i was passing out too. Does this have anything to do with the handstands im doing or is this normal
