I was by my friend's house at her front yard, she was talking but suddenly there was silence but more dense than silence, almost like nothingness. there was no sound of wind or movement. that's when i heard a faint static, looked up, and for the first time in my life i witnessed a ufo. it was a silver-white shaped boomerang but approximately 100 ft large and wide, but really thin and slim, it was heading north west but hovered for approximately 40 seconds before it made a sharp turn to north east. this was at around 5:43 pm dubai timezone (gulf). i felt static running through my fingertips, arms, and blacked out. it has been a full day since then and i still feel static energy, constant chills, and the hair strands on my arms and legs are still raised. i'll go back to examine the area further, and will report any strange evidence obtained.
