I tell this story because I don't care what people think.:
I was in the woods, tending a guerilla grow when I was younger.
Something slowly moved over top the trees, until it cast a shadow on me and my plant. It was large, probably over 50'.
I immediately thought 'helicopter' but there was no sound.
I froze in place and listened, looking up at the dark shadow above the trees.
Then it moved, quickly, causing branches on the trees to sway and leaves to drop all around me. And it was gone.
It took me ten minutes or so to make it out of the woods, and the woods were so thick I couldn't see anything. No sign of anything. no one I spoke to knew what I was talking about. No news stories.
Just one really weird experience alone by myself in the woods, doing something illegal.
Aliens? Some black ops flight program from Northern Virginia or the Naval Weapons station? Who knows, but I never had an explanation.
