The Mandela Effect is when someone has a clear memory of something that supposedly never happened in this reality, but residual evidence shows that it actually did. It was named after Nelson Mandela, who many thought had died in prison in the 1980's. According to some, his second death took place on December 5, 2013, at age 95 while serving as President of South Africa. In 2012, it was discovered that the spelling of the "Berenstein Bears" had been changed to "Berenstain Bears." Once again, in my best recollection, I do recall it being "Berenstein Bears." Psychologists describe the disconnect between our memories and realities as a "Confabulation." The term describes a disturbance of memory, which can result in the production of fabricated or misinterpreted memories, even despite contradictory evidence. It may not even be intentionally happening and can be related to brain damage.
