Fascinated by ghosts.

Studying a book on plot and structure and listening to James Horner’s “Casper’s Lullaby”.  I am fascinated by ghosts.  My character can see the spirit world.  I listen to the music and picture the sad plight of spirits trying to communicate with the living.  What message do they have?  What do they need to tell?  How lonely it must be to be at the window into the living, looking in, but unable to go back, to touch, smell, taste, or experience that world again.  How sad.  I long to help them.  The ghosts.
