Could déjà vu and the ‘Mandela effect’ prove that alternate dimensions exist?

I thought the above article was both thought-provoking and entertaining.  Full disclosure: I’m on my third Mimosa.

In WORLDS APART, our hero, Decklan, is from “out-of-this-world.”  Years ago when I started writing WORLDS APART, I was fascinated with wormholes, other dimensions, and parallel universes.  I’m the farthest thing from a scientist or physicist as you can find, so I have no authority to speak on this subject.

But as a writer and a dreamer, any concept like this will have me lost in a world of possibilities for hours.

I want to know, what fascinates you?
