The Mandela Effect is a phenomenon in which an extended quantity of people remembers something of the past that is not true or has never happened.
The term “Mandela Effect” was coined by Fiona Broome, a paranormal researcher, to explain the misremembering of Nelson Mandela’s death.
When Nelson Mandela died in 2013 many people remembered he had already died between the late 1980s and early 1990s but he was actually freed from prison alive in 1990s.
There are also clues that Mandela actually died in prison in 1991.
Look for example at this extract from a book. It clearly says that Nelson Mandela died on 23rd July 1991.
This is really weird, isn’t it?
