I know its been mentioned a million time in this post, but I have a friend whos snake did that exact behavior and within a week I belive or maybe two the poor little guy was dead. I pray thats not the case with your snake maybe she was just dancing lol. But thats always a possibility. Only difference was that his did it almost constantly if yours has only done it once or twice then hopefully shes just a weird one. best of luck to you and you little one. I lost my red tail a few months back but that was from bad husbandry on the part of lllreptile.
