The most go to conspiracy theory is the Mandela Effect isn't our memories failing us. There's people who point at the Hadron Collider's first use in 2009.
Not sure if I believe that or not but, I also don't remember ever seeing so many things that don't represent the memories I have of the way certain thigs were when I grew up.
Like Fruit of the Loom: Cornucopia on the label or no cornucopia on the label at all?
Stove top Stuffing: Kraft or Stouffer's?
Exactly. I remember being good looking. Mirror tells a different story, but I swear, that's the way I remember it!
