blood
Blood is used in horror movies to add effect. This can make the viewing more interesting and make the audience act in different ways. Depending on what horror genre the movie is, e.g. a slasher, paranormal etc, depends on what blood type/ingredients you use. If you need the blood all gooey so it can be used as a flesh wound you wouldn't use runny blood, you would use peanut butter for example to make it thick and clumpy.
