The Mandela effect

Hello there fellow steemians, just wondering if anybody had heard of the so called Mandela effect and if you have what has changed for you. Was it the lyrics of a song or a line(or word) of a movie, or maybe you have always remembered it the way it is now. Its a phenomenon that is really boggling my mind at the moment. There's loads of subtle changes out there. I'm really interested to know peoples thoughts on it. The one that sticks out for me is the scene from snow white when the witch is talking to the mirror and says "mirror mirror on the wall, who's the fairest of them all." Ive always remembered this way but if you check out youtube and other sources now, even the original vhs she says "magic mirror on the wall." Check out this vid if you always remembered it as mirror mirror on the wall.
