False memories can sometimes be shared by multiple people. This phenomenon was dubbed the "Mandela Effect" by paranormal researcher Fiona Broome, who reported having vivid and detailed memories of news coverage of South African anti-Apartheid leader Nelson Mandela dying in prison in the 1980s. (Mandela actually died in 2013,  after serving as President of South Africa from 1994 to 1999.) Broome reported that since 2010 "perhaps thousands" of other people had written  online about having the same memory of Mandela's death, and she speculated that the phenomenon could be evidence of parallel realities.
