The theme of death is often used. It could be a serial killer on the loose, or a curse that brings death to those who cross its path. The inevitability of death and the fear it brings can be a strong driving force in a horror story. Another common theme is the corruption of innocence. For example, a young child being possessed by an evil spirit. This contrast between the purity of the innocent and the evil that takes over can be very disturbing.
Isolation is a common theme. When characters are alone, they seem more vulnerable to the scary elements. Like a person trapped in a cabin in the woods with something lurking outside.
A theme of betrayal can also work well in a scary story. Imagine a group of friends in a dangerous situation, and one of them turns out to be working with the source of horror, whether it's a monster or some other threat. This sense of not being able to trust those around you adds to the overall fear factor. Additionally, themes related to the body and its transformation, such as a person slowly turning into a grotesque creature, can be quite terrifying as they play on our own insecurities about our physical form.
