I imagine some people seek out feelings of fear brought on by activities such as roller coasters, scary movies, and haunted house for different reasons. Some people revel in the fear and enjoy that biologically fear produces adrenaline. The adrenaline creates a sense of rush and excitement for them. Moreover, some might enjoy the process of conquering fear and overcoming something that can cause anxiety. Others might have a need to feel different sensation that they do not feel every day. For me, I particularly watch scary movies because I find them hilarious and not scary at all which can be a result of my conditioning.
