The basic understanding of our plot line

The gist of our plot is that there’s these four guys who are us, and we are creating a horror film trailer inside of the film using a handheld camera, a la Cloverfield/Blair Witch Project. The subtle twist is that we also use different camera utensils, like a tripod, so w came film things that we wouldn't normally see. However, one of us, who is Sam keeps having scary dreams, and the things he sees in the dream, he jots down to get out of his mind. When he tells us, we don’t believe him, until the drawings become real and try to kill us. We try to escape, however we leave the ending ambiguous at the moment, to build up suspence.
