A recent study looked at why people enjoy a good fright and found that it creates a sort of euphoria that lowers stress levels. 
There seems to be a sweet spot for enjoyment where the fright is not too scary nor too weak, but just enough to be enjoyable.

Why people enjoy being scared

Self Improvement

Being scared is enjoyable when it represents just a quick minor physiological deviation from your normal state. When it goes on too long, it becomes disturbing.
It is similar factors that make interpersonal play enjoyable: just the right amount of uncertainty and surprise. Coincidentally, it is also the ingredients of a successful joke.

Fear is enjoyed in just the right amount

A new study comparing the reactions of haunted house visitors to their heart rates seeks recreational fear’s sweet spot.

Previous studies have tracked physiological signs of fear arousal, but none have established a one-to-one correlation between that arousal and specific, actual fear events.

Andersen says that much of the research has been conducted in lab settings with weak fear stimuli, observing subjects as they experience things like scary videos. Scares in these situations tend to be weak and difficult to measure. Even harder to track in these situations is the link between enjoyment and fear.
