The document discusses potential location ideas for a slasher film, including a forest and lake. For the forest, it notes that the isolated setting allows the killer to attack victims without witnesses and that forests are conventionally used in slashers due to their isolated nature and hiding places for the killer among the trees. It also mentions that forests at night are extremely dark. For the lake, it suggests including it to add fear of nature and the unknown lurking, showing teens recklessly playing by the lake and using reflections on the lake's surface to increase fear and paranoia of something being in the water.
