We're all familiar with the concept of a "recurring dream."  But here's a serious question: could that concept itself be imaginary?  Take this "real world" example: last night we dreamt of not being surprised by two guys who suddenly had red afros.  It wasn't a lucid dream, but our dream self wasn't surprised by an otherwise unexpected turn of events because it was all a re-run, as it were.  Here's the key issue: if a dream narrative suggests that one's dream character has seen it all before, isn't that by extension a fiction because it's a part of the script?  (As James Hillman reminds us in The Dream and the Underworld, dreams aren't real.)  Now, if one keeps a dream diary and over the years there are several mentions of red afros, does this say less about dreams and more about living the same day over and over, à la Nietzsche's theory of eternal recurrence?
