Here's a good video by a professor who says the effect is being used to change the past in order to change the future. How can we change a future that hasn't happened yet? I suppose he means they want to 'steer' us into a certain particular future? Also, Quantum Theory says past, present and future are all happening together at the same time, so maybe there would be a way to change the future in that scenario.
Last night I had a strange part to a dream, where a 1965 tall Paul McCartney came up to me in a crowd of people, pointed to his lower droopy left eye, and said, "Does this look like a fake eye to you?", which I thought was weird because we've said it was his ears that looked fake so often, not his eyes. Will this forum be "Mandelized" someday to show that he had fake eyes, not fake ears??
Here's the Mandela Effect video:
"More proof for the theory that the Mandela Effect is designed to change the past to change the future."
