One time, a few years ago, this old man was burning the ditch behind our house. We didn't think much of it until the fire got out of control, and the old man was nowhere to be seen.
The fire department arrived and put out the fire, but the old man was still nowhere to be seen. My brother and I were looking out the window watching all of this.
Then the sheriff arrived, and he and the firefighters were huddled around in the same area. I went to go give an update to my mom (who was in another room, on the phone with my dad) and when I got back, they were pulling a charred corpse out of the burned up landscape.
He was completely 100% burnt to a crisp. It was the most terrifying thing I've ever seen in my entire life, and The look on his face still haunts me to this day.
TL;DR I saw a man burn to death and now I cant sleep at night.
