There was this case study of a guy who woke up one day and had memories of an entirely different life. Being married to a different woman. Living in a different house, with different kids, working a different job. They reconstructed from his memory the guest list of his wedding—the one that he remembered, but never happened. They located thirteen from his list, and all of them also had memories of this wedding that never happened. Ever hear of something called the Mandela Effect?”
