A lot of that behavior sounds like it could be seizure activity if the symptoms in birds are the same as in dogs.
With dogs, the best thing to do is to keep them calm, minimize sensory input (sounds, light etc) and make sure they can't hurt themselves. I'd imagine it's the same with birds. They get disoriented and freaked out, so they may be prone to biting. Alternatively, they may freak out and become like velcro. It kind of depends. When my previous dog (Tink) was having seizures I would shut off all the lights and tv, put a blanket over her head (to block out light and muffle sounds), and sit near her talking calmly until she came around.
A seizure is really hard on the body, it will leave them exhausted. If you see her having a seizure and she doesn't come out of it, or if she has them one after another, that means it's time to haul butt to the vet. But unfortunately, with seizures there isn't really anything you can do but ride it out.
I'm no expert, so take what I have to say with a grain of salt, but this is stuff from my experience with dogs that I would imagine applies to birds too.
