Nyctophobia

Nyctophobia is when someone is really scared of the dark. Basically, nyctophobia is a fear of darkness, which can make someone feel anxious or scared when they're in a dark place or when the lights are turned off. Just like how you might be afraid of monsters hiding in the dark, someone with nyctophobia might be afraid of something bad happening to them when it's dark. But just like how your mom or dad might reassure you that there are no monsters in your room to help you feel better, people who have nyctophobia might need some extra reassurance and support to overcome their fear.
