PPP Stimulus and Pitch

This is one of the four important parts of the curriculum for IB Theatre. From a few random pictures, music pieces, or random anythings, we need to create a pitch for a play or production that was inspired by those. I am incredibly lacking in the imagination department so this is desperately difficult for me. Our group chose this song about ghosts or something as our stimulus and I have no idea where they came up with creepy ghost story about a girl who seems like a freak to the rest of the world. The girl was to be shunned by society because of her clairvoyancy only to meet someone that finally understands her and dies. I personally, thought the song sounded rather happy and I was leaning towards Casper the Friendly Ghost or whatever that movie is called. But I guess not. Anyways, the way people interpreted their own stimuli was really interesting. Everyone had such different ideas. The one that Celestine and Anna's group had was really cool but I think letting the audience choose how the story will go is a bit confusing. What if the audience members don't agree? How are the authors going to keep all that straight? I guess it would be fun to see how it works out though. I have no idea how anyone expects me to do this on my own next year especially if there is the need to understand staging and lights, too. Those are not exactly my forte.
