What is actually happening in this video??

I've literally never seen anything like this on tiktok before. Some people in the comments claim it be be psychosis while some people side with the creator and kind of explain but not really explain what she's talking about? What do you all think, is this cause for concern mentally or a legitimate glitch in the matrix.
