I have one, my two brothers and I were in the cemetery my Dad is buried in, I, being 6 or 7 years old, and having to tag along in my brothers 64' Impala, saw a ball of light the size of a softball wandering around the cemetery, I pointed it out to them, I think there was two girls with us also, they all stopped in their tracks. All of us just stared at this thing floating around, it passed within 20 feet of us at one point. That's when my oldest brother said "let's go NOW". We jumped in the car and tore outta there like a bat outta hell. Once we got on the main road, the object closed the distance we were to the road instantly. It followed the car for about 1 mile and then stopped it's chase and slowed down and slowly went back to the cemetery. We did not speak of this until the next day, and we thought it could have actually been our Dad shooing us away to go home (it occurred at night). One thing is for sure we all decided that thing was not fake, nor was it random, it made turns and accelerated and decelerated, it passed through some of the head stones but went around others, freakyist shit I've ever seen!
