I think that this Mandela Effect may very well be a result of our consciousness shifting into the new age of Aquarius. Some of us may still have conscious memory of the old age but I think that time space is resetting itself . Sounds a little sci fi or a little metaphysical but for so long people have waited for a consciousness shift (in y2k and 2012 )without understanding what that meant and how it would affect people and we went through those times “thinking” nothing happened … now some of us are looking back and noticing that the linear timeline we thought we were on has shifted and reality is not what we always believed it to be.
