Always Wondered - Why We Dream?

On this episode, we explore why we dream.  What exactly do those nightly movies in our brain mean?  Also - what were the first words ever uttered when man invented brand new ways to communicate?  From print to broadcasting to the internet, you'd think they'd be profound, right?  Well, think again!  Plus - what's the origin of the phrase "waiting for the other shoe to drop"?  How did falling footwear come to mean bad news?  Hear all about it as host Rick Peterson answers more of the questions you've Always Wondered about.
