Storms from the East

I was in the Midwest part of the country, sitting in a large open plain on a lawn chair, looking at what appeared to be a soccer game. Other people were sitting with me. Suddenly, dark black clouds came from the south and southeast. I saw lightning in the distance and knew a storm was approaching. They looked far enough away, and it seemed we had at least ten minutes before they arrived. As soon as I sat back down, the clouds supernaturally accelerated toward us. I was shocked by what I had just witnessed. The wind was now blowing hard, and heavy rain was pouring down. Lighting was striking all around us. I ran inside a nearby abandoned building for shelter. I called for the other people to accompany me, but they ran toward their cars. I warned them not to get in their cars, but they would not listen. I checked all the windows inside the house to ensure they were secure.
