memorable

I have been searching for a place to write my dreams...forgive me if they seem 'un-cool'.
This is a peice of my dream from last night;
****
There are people all around me in my classroom, a mixture of the living and the dead. Some are ghosts and some are just normal. But strangley everyone can see them and aren't freaking out.
This is a world that knows about ghosts and lets them live among its scociety without question. These ghosts start out looking the same as they did before they died, no goulish features or anything. They can even touch and grab things without going through them.
But they don't stay like that forever.
If the dead interact with solid things, including people, to much, they begin to get this weird, crusty film over whatever part of them touches the most mortal things.
I remember talking to a dead girl, who was floating infront of me looking at her hand. She was describing to me what her hand looked like, even though I could see. "As dark and rouch as tree bark, but it has little sparkling things like diamonds in it. Weird."
And that bark thing that slowly began to grow all over their bodies prevented them from being able to interact with the living world for good.
And the worst part was that my best guy-friend was dead, too. I still don't know how he died in it, but he had just turned into a ghost and didn't have any simtoms yet of getting all, ghost-bark-like. I didn't want him to end up like that, but I also remember thinking, "If he's going to live forever, will I have to die to be the same for him?"
And then I recalled all of the ghosts having no film on they're faces, and I thought, "What happens when they kiss people?"
And then I woke up, and now I don't know whats would have happend if I hadn't.
I'm gonna tell my friend that he was in my dream. And he was dead.
