I was driving and came to a red light at an intersection. out of the corner of my eye i saw a bunch of lights and out of the tree line came out this circular object with a bunch of light around it. at first i didn't really know what it was, i knew it wasn't an airplane because of the obvious shape. as it came out of the tree line, it traveled across a straight path and the left a trail of light as it glided across the sky. i couldn't believe what i was seeing and was completely fixated and my body felt almost frozen. as the object moved across the intersection it disappeared as it got further away from my eyesight.
