Mandela Effected or Compromised Memories?.

Mandela Effect: The top 500 list

Mandela Effect Database

The Mandela Effect is where a group of people remember something for which there's no evidence. It's named from many remembering Nelson Mandela dying in prison in the 1980s and not 2013.

Rather than accept their memories are faulty, many of those experiencing this claim it is no co-incidence so many are affected, and say the past has somehow changed. The causes for this are unknown, but theories ranging from CERN experiments to it being evidence of time travel are suggested.

Here's a list of many well-known ones, sourced from various internet users, forums and direct reports. Bear in mind some will apply to certain people and not to others. The "Affected" value shows the percentage believing the alternate memory from the survey.
