Well, my dad said many years ago that he saw UFO when he was young - that had to be like 40 years ago or something.
He said he saw an golden object of shape of bullet - I can't confirm this.
My friend also experienced unusual event, but this was just a strange sound - that was approaching him very fast. He was on the car park on the middle of nowhere in the forest.
He run away of course - so there was no close encounter.
He also was sure that he has an implant in his arm - little object that appeared suddenly.
But this was never tested.
