There are two extreme attitudes regarding dreams:  The first is to see significance or dire portent in every dream ever dreamed.  The other is to discount the value of dreams altogether.

This is what The International Institute for Dream Research has to say: - "Actually, each of us has a built-in device to evaluate experiences and the information we encounter each day.  We are born with this process.  It is called the dream.  As our lives progress, we interact with others.  These interactions shape the structure of our lives, individually and collectively.  We draw meaning and memories from these interactions.  The question is: ‘How does the individual as well as society organize and remember life as it unfolds?'  Dreams provide the route to understanding."*

Whatever our opinion concerning the significance of dreams, experiences such as that of Frederick Kekule urge us to take at least some of them seriously.  Most could be no more than the effects of indigestion.  Others may be the mysterious workings of the subconscious mind.  Perhaps our wakeful thinking is plagued by too much distraction, and our subconscious takes over when we are in a state of rest.
