Mind over matter?

Today, I talked to a friend about my need to “hibernate” intermittently.  By hibernating, I basically mean becoming a recluse.  I thrive on these periods of nearly absolute isolation.  This is not a concept that many of the people around me seem to understand.  I love retreating into my inner mind.  It is an endless abyss.  My friend responded by expressing her belief in how each individual’s personal lived experience can change the universe.  This is an idea that I had once briefly dabbled with.  It reminded me of the conception expressed in Dan Brown’s The Lost Symbol about how the thoughts of the masses can alter the natural world.  I would like to explore this notion further.
