This footage was found within hundreds of miles of the Paris Catacombs. The video shows a man exploring the catacombs and his breathing slowly gets faster until he starts running. He is panicked and drops his camera (as seen in the last gif) which was his only source of light.
There is no clear reason why or what he is running from. It is strongly possible that something spooked him out or that he is running because he panicked due realizing he is lost. There is a very strong possibility that he got lost and died, especially after losing his only light source.
This was on ABC Family?
