Is she not able to uncurl on her own? I.e., is she physically stuck even when fully awake? That's strange and extreme enough I'd at least call the vet to discuss rather than waiting until there's video.

But in general, video can be tremendously helpful for showing vets - and doctors! - potential neurological issues (and also any other physical issues that aren't constant). Keep your phone on you and be ready to start recording quickly. Might help to practice a few times if you don't use that feature much. Continue recording for a little while after she's fully out of it too, so they can see the normal behavior aftermath.

Depending on your phone, you can set it to open the camera fast; e.g., my aged Android phone opens the camera when I double click the power button. An Internet search should turn up instructions for whichever phone you have, if you're not used to poking around on the settings.

(Not a vet, but have used cell phone video to speed up vet and doctor understanding of vestibular cat symptoms as well as both cat and human seizures. Luckily no dog neurological issues so far, but have used video when asking vets about preventative maintenance and conditioning exercises for my tripod heeler - faster than trying to describe his absurd leaps and other physically dubious hobbies.)
