Top Ten Cases of the Mandela Effect
The Mandela Effect is a phenomenon where a large group of people share the same false "memory". They remember an event that did not happen or the same specific detail about something that is inaccurate.Conspiracy theorists point to the Mandela Effect as evidence of multiple dimensions or alternate universes. More traditional thinking attributes the Effect to the mechanisms used by people's minds to process, encode and retrieve memories. Regardless of what causes it, the Mandela Effect is real and here are the top ten examples of it.

That's actually pretty easy to explain: in the context of the movie, it was not necessary to address Luke by name as it was said in the middle of a conversation, as a response to Luke's previous line. However, over the years, movies, T.V. series, games, shows and even people in everyday life parodied and referenced this scene, and said "Luke, I am your father" in order to make clearer where the quote originated from, sometimes it wasn't even in a dialogue that would have allowed the phrasing "No, I am your father".
What you remember isn't the original movie quote, but the parodies of it.
I personally believe this should be higher on the list, mainly because it fooled so many people in the past, and to be fair, it fooled me as well for a long time!
When I was young I remembered Luke, I am your father. Then when I was a little older I remembered" No Luke, I am your father." Now I know it's "No, I am your father."
This is the most famous quotes! On t shirts, in books EVERYWHERE. We all thought it was Luke, I am your father.
Oh my gosh, I swear up and down and back around that they're the Berenstein bears. I had a friend obsessed with them -- they were everywhere! I read them! And they were stein's I KNOW IT. Someone's changed it, changed all of it, maybe even as a test to pull some 1984 stuff on us, but I'm not going mad, the war was with eurasia and the Berenstein bears is the true name!
Its always been Bernstein bears! But I guess I'm wrong.
Wasn't it always Berenstain? Childhood anyways
I personally believed that it was Berenstien but NOPE I was wrong.

In the "Snow White" movie by Disney they say "Magic Mirror", but in the original Grimm fairytale it's "Mirror Mirror".
Accurately translated from German it'd actually say:
"Little Mirror, Little Mirror on the wall, who is the most beautiful in the entire land/country? "
Another famous movie quote. Who else thought it was Mirror Mirror on the wall?
Much like "Skechers", you'd assume it would be written "Febreeze" if you only heard the name without reading along.
Maybe people just reed to fast.

I played the game all the time with my grandma growing up, while I don't remember the main icon having this feature, it seems like some of the cards did.

For this one, I have no explanation, and am still looking for why everyone, including me, thought he had a black tail tip.
I remember to the bottom of my tiny heart seeing Jiffy peanut butter!
I remember, "Jiff", not "Jif" or "Jiffy".

This can be explained by not having read close enough. If you just heard the name by itself without reading it, you'd assume it's "sketchers", because there appears to originate from the word "sketch".
I don't really believe this one, but it's pretty populat. People think it used to have a T
A lot of these famous movie quotes have been altered by parodies and references in other media, because the line was used out of context.
In Forrest Gump he said "My mother said life was like a box of chocolates."
Now, if the line is quoted in a series, movie, game, comic or online, they just leave out the "mother" part and directly quote "life is like a box of chocolates". A lot of these quotes became so classic because pop culture frequently referenced them. However, they did so without the entire context of the movie and therefore have slight alterations so it made sense to them. What people remember best is not the original movie but the many parodies of it. Personally, I knew most famous movie quotes before actually seeing the movie they originated from, so naturally, I'd rather remember the altered, quoted version.
I think they say it both ways. Forrest says "Mama always said life was like a box of chocolates" while his mom on her deathbed says "...IS like a box of chocolates.
Never seen the movie but I believe that it was "Life IS like a box of chocolates"
I swear it used to be lucy you got some splainin to do! I am shook!
I look at a picture of it and her smile was HUGE some people thought she had a straight face, but I remember a tiny smile but not that big!
Thiy is probably because "Sex IN the City" sounds a lot more natural and rather like what you expect from a movie/series title than "Sex AND the City". Also, people don't talk distinctively. They say something like "Sex 'n the City", and if you haven't seen the show or read the title before, you'd rather assume they said "Sex IN the City".
Never seen it nor do I care but somehow, I remember "Sex IN the city"
They did say that in the movie, but it was not scripted, it was one of those famous improvisations, that the director kept in the final cut
This one freaked me out! I always thought it was Chic-Fil-A!
Holly crap, you are a genius! I never realized that!
