Phobias

A phobia is being scared of something that isn't meant to be scary or doesn't harm you.

A fear is being scared of something that is actually scary or something that can harm you.

I have the fear of insects which is called Entomophobia. Meanwhile being scared of only spiders is called Arachnophobia.

There are also quite weird phobias like Russophobia which is the fear of Russians, and Allodoxaphobia which is the fear of opinions and it is quite rare.
