Welcome to filmmaking.net, Dmitri!

I, too, think it'd be interesting if you could pull
it off. I hope you try. I'd love to see the finished
movie.

The aim of an argument or discussion should not be victory, but progress.
Joseph Joubert, essayist (1754-1824)

Keep brain storming. It sounds like a hard concept to achieve but it's definately original.

Thanks guys, right now I'm working on it as a short story.
I'm even doing a viral like Cloverfield's.
Here's a treatment:

Hell, Michigan. Summer 2009.

5 friends, Anthony, Ashley, Brett, Chet, and Sarah are on an extended weekend getaway to Chet?s grandfather?s old cabin. Chet?s grandfather warned him before his death 6 years prior never to use his cabin, under any circumstances. He claimed he had seen ?terrible things? there, and anyone who entered would struggle to get out. Chet, who was 13 at the time, disobeyed his grandfather, partially because he didn?t believe his claims, and also because he didn?t care one way or another. Brett, however, was cautious about venturing to the cabin?s area, as he is a devout believer in the paranormal, and has studied in the field of extra-planar spirits before. His girlfriend, Sarah, convinces him to make the trip with her, to which he agrees; in spite of this, though, Sarah breaks it off with him whilst en route to the cabin. Brett, now in a deep depression, vows to himself that he will strike revenge upon Sarah.

Not long after the guests arrive at the cabin and unpack, they start hearing things coming from outside. One plate in the kitchen fell to the ground and shattered with no wind current or human activity by it?s side. What?s causing this trouble? No one quite knows, and Brett is too pre-occupied with Sarah to care. Later that night, at precisely 2:13 A.M., all of the guests are awakened by a loud, blood-curdling scream coming from the main room. Terrified, they file out of their rooms one by one and head into the room. To their horror, they discover that walls have words written in blood on them. They don?t make sense at first, however ? they are later discovered to be that of a riddle. But a riddle for what? All 5 of them must team together to solve the riddle and find the answer within the house. They try to call outside the house via phone lines ? disconnected. They try to get out through the windows ? the glass has been rendered un-breakable, the doors unpassable. They are trapped, and must band together if they want to survive and break free of the houses ?clutches?. One by one, riddle by riddle, they guests are taken through twists and turns of not only the houses history, but their own history, their bloodlines, their past memories and even their future experiences.

What has happened in this house? What IS happening? What WILL happen? Can Brett?s studies in extra-planar spirits possibly help them get out? Is there something more to this than just a cruel joke being played out somehow? Is it revenge from Chet?s grandfather?

Spirits Divide.
