Dude it really fucked me with me when I first woke up to all of it. But it's nothing to stress about, we live in a multiverse with many different timelines running parallel with many different versions of you and I. "God" created it this way so we could expand and grow in the most efficient way. As we are nearing graduation from this current "school", the parallel timelines are just converging in preparation for our "shift" into the next higher octave of existence (what we've always been told of as "heaven"). Our ability to notice this Mandela Effect is just another "alarm clock" we built into this matrix to wake us up at a certain point. It's all very good stuff, nothing sinister. Synchronicity is another of these "alarm clocks" that you'll soon begin to notice more and more as our solar system moves farther into the Photon Belt which is triggering all of this. Have fun with it all, shits only gonna get weirder!
