Have you ever been absolutely sure about something, only to find out you were wrong—but others remember it the same way? That’s what the Mandela Effect is all about. Coined in 2010 by Fiona Broome, a paranormal researcher, it refers to when groups of people share the same false memory, like a brand name being spelled differently or an event happening that never actually did.

From the North Pole’s surprising secrets to crispy snacks and legendary music logos, we’re unpacking the 10 weirdest Mandela Effect Mysteries.
