I was walking down the street and i decided to look up at the stars as i always do when i saw a triangular object flying past. it had 3 circular lights that would pulsate. 2 of the lights were a greenish color and the other was white. i was very nervous when seeing it because when i would walk and then look back it would seem to stop midair. i decided to walk faster until it was out of my sight and upon returning home it was nowhere to be found.
