Fear of the unknown. That
feeling you get when you’re faced with anything unfamiliar — not just people from other countries, but places, ideas, or situations that make you go “this isn’t right...” Usually shows up alongside things like nyctophobia (fear of the dark), where the real issue is uncertainty, not danger.
Not to be confused with xenophobia, which is more about hating or fearing foreigners.
Incognophobia is fear of any unknown — even if it’s just a job interview, a different vibe, or a blank map.
