The video is actual footage of the tornado that gave Lucy Lilapsiphobia

Lilapsophobia:
Lilapsophobia is an abnormal fear of tornadoes or hurricanes. Lilapsophobia is considered the more severe type of astraphobia, which is a fear of thunder and lightning.

Most people in Oklohoma don't have this problem. Given they're used to it. Me on the other hand, will lay down in their closet and sob at just a tornado watch. My name is Lucy Heartfillia. I'm 17 years old, I live in El Reno Oklohoma. I attend Fairy Tail highschool as a Junior, and I have Lilapsophobia. When I was a little girl, a tornado, an EF5 tore threw my home town. Many people lost their lifes that day. Including my mom. Me and my father have been alone, and I cringe at just watching a video of a tornado. Thankfully, my father is there to help me through it all. I never thought I would meet someone in Okolohoma with the same problem as me. I still haven't, but I did find someone who knows my pain. His name? Natsu Dragneel.
