Imagine thinking you know something for certain, only to find out that reality is different from what you remember. This is the Mandela Effect, a phenomenon that has captured the imaginations of people around the world. It refers to the collective misremembering of an event or detail by a large group of people, and it’s more common than you might think.

From the spelling of brand names to famous movie quotes, the Mandela Effect has been used to describe a range of examples that challenge our perceptions of what’s real. Some people even believe that it’s evidence of parallel universes or alternate realities. Others argue that it’s simply a result of flawed memory or the power of suggestion. Regardless of the cause, the Mandela Effect is a fascinating and mind-bending concept that can make us question our understanding of the world around us.
