July 2,2016,9:30pm...Arlington,TX...went out back to smoke cig,I always look at stars while I smoke,was looking at plane which was about 10,000ft or so up,when from my left came a very large,translucent oval only about 500 feet or so from the ground,moving at an estimated 700-1000mph(without any sound whatsoever).It had to be only 500 yards or less from me.It flew across from behind me, into my view and across the sky,under neath the clouds.Southeast to Northwest,slightly ascending.It took only 8-10 seconds to fly across entire unobstructed sky.Absolutely positive upon seeing this that there is NOTHING on this Earth,that could be confused with it.It was like I was watching a movie because it was so surreal.Extremely large,fast,and intelligently controlled,without a doubt.Here's the strange part,two hours later,while asleep,I had the most intense sleep paralysis event ever.(had other type sleep paralysis events twice in lifetime,but was very young).in the event ,there was some kind of "force" outside my window,observing me.I just thought it was ironic,that the two happened within two hours of each other.thank you
