Thanks for the replies, guys. 8 hours later, she is finally back in her hide being normal again.
It did seem like she lost where the rat was at in the water bowl, because it was almost completely submerged... And then she just eventually totally lost interest in it. The thing that struck me as weird last night is that I actually did take the rat out of the bowl after an hour, heat it up with a blowdryer, and plop it in front of her, but she didn't care for it... while focused hungrily on my hands and kept trying to find a way out. LOL.
