when something happens to you that you can't understand in conventional terms or even comprehend properly
Generally when that's happened to me in the past there was alcohol involved, or back in the 60's something else.

The advantage of getting older, is that eventually you become a store house of information to explain more, but as I passed 70 I decided that if it isn't going to stick you, bite you, make you sick, be pleasurable, or financially rewarding, then it really doesn't warrant my time to figure out, I leave it alone, and move on.
Not in this case, lol. OK, OK, so here it is.
Was winter 1973, and I was visiting my Mom in Louisville, AL in between quarters at college, probably Christmas/ new years break. It was a cold, clear evening and I had borrowed my sister's 1970 Chrysler Cordoba
And me and my childhood friend Tommy (who was also home from school) were tooling around in that ride for the evening, driving aimlessly around the local country roads. Around midnight, we pulled into Robertson's Mill, which was an old abandoned water-powered mill, with a dam still in place and a mill pond. Tommy exited the car from the passenger side and I got out and walked about 50 feet behind the car, ostensibly to pee. But I had a prank in mind. In the pocket of my surplus army field jacket was a couple of quality bottle rockets and a lighter. My plan was to launch the rockets in his general direction as he was relieving himself, and I could barely contain my laughter. However, that prank was suddenly the furthest thing from my mind, as several things happened at the same instant: A ball of bluish-white light, seeming about the size of a soccer ball, appeared perhaps 6-10 feet from Tommy and head-height. It began pulsing at about two beats per second and I was instantly transfixed by it. With each pulse I could hear a "click"
inside my head. The light was exceedingly odd and it didn't cast shadows. I instantly had a "fight-or-flight" panic reaction, but then somehow, instead of running the opposite direction from the threat, I could not help but walk toward the car and the light, until I remember standing with my hands on the top of the driver side of the car, just staring at the light- which was only maybe 15 feet away at that point. My perception was that "it"
knew my every thought and every experience in life-basically my entire existence- in that moment. And that's all I ever remembered until I was sitting in the car with Tommy, who was in a fetal-like position against the passenger side door. I said, "Tommy, did you see...", and he said something like "lets get the hell out of here!!". Well, we motored on in silence, I dropped him off at his parents and I drove back to my Mom's place. But things were never quite the same. Tommy would never discuss that night with me, even though I asked him to every time I saw him subsequent to the event. I re-connected with him on facebook a few years back, and I couldn't wait to bring up the light at Robertson's Mill all those years ago. But alas, it was a no-go.
