I had exactly the same thing, but a lady. She told me the vibrations were her guide. But, the most amazing student ( not mine ) was a guy taught by a lady I was coaching , not with him, and she used to take him dancing to a very large social in St. Pete. He NEVER bumped into people on a crowded floor. Reminds me of a special I watched last year about a man who rode a bike on the road and said he used echo feed back. I believe they planned the route by distance and buildings .
