I was driving home, passing downtown dallas, and since it was kind of dark and rainy, i tended to bring my attention to anything that lit up the sky. i saw something that looked like it was a plane at first, and i looked at it, but then i noticed that it was flying wayy too close to the ground compared to where a plane would normally fly, especially around tall buildings. then i noticed that the "plane" was also flying way too fast for it to be a normal plane, and when it stopped to the side of the highway and hovered for a little bit, it kind of freaked me out. then, it turned almost completely sideways, but kept moving the same direction that it was moving before. not to mention, this thing was rectangular in shape and had four lights on the bottom of it that were really bright compared to everything around downtown dallas. i tried to take a picture of it, but right as i did i went over a bump in the road and all you can see are blurry lights. when i looked back up, it was gone.
