I have had this dream most of my life.  I am running through the White House to let JFK  know that people are going to kill him.  He sits in his rocking chair and laughs at me.  I get so frustrated and can't get the words out.  And then it happens.  My daughter interprits this as the hopelessness everyone felt when he died because there was nothing they could've done to stop JFK from being assassinated.
