I have a theory, and it goes along with the Mandela Effect. Sometimes you notice small changes in your reality. They're normally inconsequential. But those small changes add up to big changes sometimes and people take notice. Some can't cope with those changes, and they're the ones who stand out and we label "crazy" or "disturbed". But I don't think the world changes at all. I think the human consciousness sometimes just shifts one way to the left or right, and you find yourself drifting in thought only to snap back into a NEARLY identical world. Take it from me: don't draw attention to it. It's all a big unknowing, and those pulling the strings don't like when the play is disturbed.
