I was letting my dogs out for the night when i say a bunch of shapes that looked like dull white party balloons and they were outlining a shape of an object. the object its self was invisible and was from how i say it outlined irregular in shape. they or it was moving incredibly slowly and after a bit it just seemed to disappear. when i saw it i couldn't tell if it were a bunch of balloons tied together or what but when i thought back on it who lets go of incredibly dull white balloons in the middle of the night that disappear. i thought of my friends story of a ufo he claims he saw and this sounds like it could possibly be legitimate.
