I was camping at lake wilson with friends and family. i was walking around about half an hour after sunset with a group of 4 friends. one of them noticed the light first; it was floating over the water near land and seemed to be someone flying a drone. we could not tell for sure the size of the light or how high up it was, but if drone-sized would have been about 200-300 ft. elevated. it was blue in color but started flashing and changing colors a short while after we noticed it. it started moving slowly straight up and down while still changing colors. then without warning it shot to the right and stopped, then went to the left and stopped. it was increasing its speed and making very strange movements that we determined was impossible for a drone. where a drone would slow down before changing directions, this light was bolting around almost as if the laws of physics didn't apply to it. i was afraid and headed back to the camper with two others, the remaining two following behind us. we didn't stick around there long enough to see what happened to it. i was a skeptic before this happened, but now i just don't know.
