Not quite the same, but very surprising. When I was in my fifties, and living and working fifty miles from my home town and primary school, a young lady came to my workplace prior to starting her new job there. She stopped and chatted to me for a while. There was such a familiarity that I finally asked her if her mum was a twin. She was very surprised, but replied that she was. I asked - ??? or ???. She told me which one, hardly believing that I could have guessed that. She looked and sounded so like those twins whom I hadn’t seen for over forty years that it just had to be one of them. She couldn’t wait to tell her mum and aunt. Interestingly, she said that everyone told her that she looked like her dad!
