Its apparent to me thats what happens when ome of these black geometric ufos approach someone from below, such as on a mountain, but time stops or dramatically slows for those below the craft. I believe what people express as "abductions" or "lost time" is an artifact of the gravitational drive mechanism.

If someone was messing around with gravitational fields what other things would it affect or show up on? Could average people detect it?
I think average people can't figure out what happens to them so they just chalk it up to something unimportant. The nature of a spacetime warp field controlled by an ancient intelligence is that its impossible to reproduce and difficult to analyze, so its beyond the reach of scientific investigation. Most people experience it as lost time, and they excuse it with alternative explanations. In addition, it doesent happen to everyone, or at random, because its not a natural phenomenon.
Or maybe some super advanced species has found a way to tap into human conscious... if I was a super powerful alien species I wouldn't want physically travel through the universe, too much time and work. I would find a way to travel telepathically and just jump into the conscious of other sentient beings.
Im not speculating, rather connecting several personal experiences with reports from friends and family and the recent whistleblowers. They all mesh, and now I realize why the percieved shape of the crafts are inconsistent.
