Agatha Christie might have experienced this. In 1926, her husband Archibald had been having an affair with another woman and asked her for a divorce. One night, she left her home at night, drove a little far. Her car was found abandoned. When they searched for her she was found 11 days later in a hotel in Northern England staying under a false name with no recollection of who she was. But, there are some people who think that she did all of that deliberately just to embarass her husband.
