Sometimes I get things in my head that I just need to get out into the world.  I suspect a lot of people do.  Ideas that bite and nibble at you until you do something about them.  Usually it's words.  Sometimes it's art projects, big and small.  Some I get done, some I abandon, some I say "someday".  The most frustrating ideas are the ones that I don't have the tools for.  (Yet.)  Some of them are things I know I can't bring into existence.  Ones that are just so much essence and spirit and energy that I revert back to words in the hopes that someday I'll capture some small part of their being.  It would make me sad, those things, except that I know that they exist anyway.  Just not here.
