>>2861801the mandela effect is when a large group of people misremember something, it's got nothing to do with dimensions or whatever it's just psychology/sociology
peoeple had thought nelson mandela died several years before his actual passing, and because of mass retardation and american stubborness noone wanted to admit they just didn't remember correctly. therefore, when this happens, it's called the mandella effect.
you can cause it to happen with suggestive questioning, for a basic example "do your parents know you are gay?"
ask enough people something suggestive and some of them will beleive it
frank herbert wrote a book about it and everyone that read it seems to think it was about magic because noone wants to admit that deep down it actually does say gullible on the ceiling
