Myself and 6 other people were in the back yard, when a round disc appeared above us, it stayed above us at about 50 ft. i could have thrown a rock and hit it! not only did the craft not make any noise, but it seemed to absorb all other noises! we all stood motionless for 20 minutes staring at the ufo! my brother and i often discuss the event and the complete absence of sound and lack of ability to move! i have no doubt we were given something that day! the sun started to go down and our neighbors lights hit it and it started moving, we snapped out of it and it slowly started moving!
