Tetraphobia

Tetraphobia is a fear of the number 4. People who have this fear might think the number 4 is unlucky and will avoid things that include it, like certain buildings or times of the day. For example, some people might not go into a building with the number 4 in the address because they think something bad will happen. This can be really hard for some people, but there are things you can do to help manage your fear.
