It started out as a normal dancing video, but things went south when a woman captured a man breaking into her apartment on camera.
A woman from Maryland named Hannah Viverette was filming her dance routine on her phone as a man scaled up her two-storey balcony and entered her apartment.
The terrifying ordeal captured on camera has been viewed more than 44 million times.
In the clip, Viverette spots the man and repeatedly asked who he is, with the man seeming to reply in Spanish. She asks him to "please get out" before running out of her apartment and knocking on the door of a neighbour to help and calling police.
