(apologies...I didn’t read the whole article...but I’ve found this guy’s disappearance interesting) https://en.wikipedia.org/wiki/Harold_Holt
My stepson had an episode while in college, where he disappeared from a party, indoors, after talking to two females no one seemed to recognize. He turned up the next day wearing only his bluejeans shorts and one sock, behind a quickstop station in Knoxville, TN. To this day, he has no recollection of how he got there from Murfresboro, TN. At the time I had been reading of the strange disappearances of young men in college towns, turning up dead in bodies of water, sometimes a week after disappearing but showing signs of being in the water only a few hours. It spooked me good, don'tchaknow!
