The Mandela Effect is a term used to describe changes in the physical world that do not correspond with some people’s memories.
Here are a few examples:
Some people look at the children’s books called the Berenstain Bears and remember them as the Berenstein Bears.
Some people remember the artist Prince having lyrics that begin with “Dearly beloved, we have gathered here today to celebrate this thing called life” though it is currently “Dearly beloved, we have gathered here today to get through this thing called life.”
Some people remember a bookstore called Barnes and Noble while others remember a bookstore called Barnes and Nobles.
Some people remember Darth Vader from Star Wars saying “Luke, I am your father” while the current version is “No, I am your father”.
There are many sites on the web dedicated to going over specific Mandela Effects that have been discovered recently.
Why is it happening? First and foremost, you are not crazy. There are two universes that have been merging as the physical world and the spiritual world have been balancing. Both universes are almost identical but have small differences. During the merger, these differences have to be rectified so one of the perspectives is agreed upon for the final merged universe. The two universes take turns with which final perspective is used.
Feeling like the world is not the world you grew up in? While you are correct, do not worry. This is part of a greater plan and the result will be a unified understanding / coexistence of the different rays of light and their various forms of happiness.
