People are afraid of their imagination. Ask someone to write fiction and they fold into their embarrassment! Imagination is the product of your experiences, your thoughts and your dreams. To turn your imagination into a physical piece is similar to opening a wound and ushering others to watch the blood run and think of the fall you must have taken. People are ashamed to have such wounds - to have ever been vulnerable or weak. This weakness being used to create something is seen as a sort of permanent, public reminder of your faults instead of being seen as what it really is: something very powerful.
The brain appears to possess a special area which we might call poetic memory and which records everything that charms or touches us, that makes our lives beautiful.
