Quantum Weirdness 106: Are dreams real?

 “Reality is wrong.  Dreams are for real.”–Tupac Shakur

It has been advocated–I can’t recall by whom–that our sleep dreams may actually be real events in an alternate universe.   I doubt it;  that’s too far over the top for my taste.  But the following unusual dream–one I’ve actually had–will serve for now as my final installment of the Quantum Weirdness Primer.   It’s a fitting intro to my next two conjectures, both of which deal with the possible nature of consciousness in relationship to quantum physics.  The dream was short and unexciting, but opened up a Pandora’s box of questions.

The Infinite Office Building

The Flatiron building as it appeared around the time of my father's birth in 1919.  It wasn't actually in the dream, but it's just too cool not to include.

I am working in an art-deco era office building in the Flatiron District of Manhattan.  It is a beautiful, clear spring day and the New York skyline fills my panoramic view.  I get up to go to the water cooler when a realization hits me.  This is an infinite office building with an infinite number of floors.  Every floor represents an alternate universe–an infinity of them.   Every possible universe that I could, or possibly do exist in, is here.   I ponder the implications and head toward a back staircase to explore.  Which way should I go? Up or down?  Where will it bring me?  But a chilling thought hits me just as lift my hand to open the exit door leading to the stairs.  What if I can’t find my way back?  Sure, this specific universe that I currently exist in must reside somewhere within an infinity of universes.   But by definition, if I explore starting from this one, there will always be a finite number behind me and an infinite number ahead of me.  I would likely never find my way back within my lifetime, or perhaps even an infinite number of lifetimes.  I lower my hand, go back to my office,  and wake up.

The dream is reminiscent of David Hilbert’s concept of the Infinity Hotel, an explanation of which is in the entertaining short video below.  Strangely enough, I first heard of this idea two weeks after having the Infinite Office Building dream, when I read about it in detail in David Deutsch‘s The Beginning of Infinity.  In any case, the conclusion I reached from my hesitance to explore, was a realization that maybe it really doesn’t matter how many potential or actual universes there are if we are only conscious in one.  Or one at a time.  Or does it?  I’ll discuss these enigmas in my next two Millennium Conjectures, after a finite number of intervening posts.   [Video credit: The Open University]
