Omigosh. I just remembered what a phobia I used to have of clowns back when I was a kid. Not just a fear, an outright phobia. Clowns were evil. Clowns were scary. Clowns were like... worse than monsters! I even used to have nightmares about clowns.
The odd thing is, fear of clowns turns out to be not uncommon. But I didn't know that back then. All I knew was... I was terrified of clowns.
