I've done dowsing. I don't have a clue as to how it works, but it does work. Freaked me out a bit when my Dad showed me how when I was 17. My geology teacher had said it was a myth, and I talked to Dad about it. Might be something with magnetic fields, might be magic powers, might be something weird in my brain. Might not be anything I've considered. I have used it to find sewer and water pipes. Seems to work for underground wiring, too. I have never done a serious study to see what limits it has, nor have I tried the forked willow twigs the Appalachian water dowsers use. Dad showed me with a couple of pieces of bent coathanger wire. Last time we did it together, when I was home on leave from the USAF one time, we found the plugged drain line for the septic system at his house, and dug up the plastic pipe, and found where the RV parking on top of it had collapse and blocked the drain line. That's been close to 40 years ago.Plus, there are a few, especially here in Oklahoma, that believe in things like 'dowsing' for water or lost items. Is it real or just hocus-pocus?
Had a friend once who could tell you a bit of the history of an object once she'd held it, too. Dropped a knife I'd gotten from my dad into her hand once, and she blanched, and dropped it. Said someone had committed murder with it. I don't know about that, but Dad took it from a guy who attacked him with it, when he was on sentry duty as an Army National Guardsman and reported the guy for returning late from a pass. He had at least tried to kill my dad with it. Dad was a little skinny guy, but strong as heck, and not someone to be messing with.
