 You're standing at the grocery. You have a funny sense someone is staring. You look up. Someone is looking at you. It isn't the question of why they're looking at you. It's your sense that you knew they were looking at you. We have knowledge, but we don't know how we have it. And I compare this. I bring this into a book about UFOs because the UFO pertains to some knowledge that we can't fully explain. But the phenomena bring us face to face with it.
