What was your biggest childhood fear and do you have it to this day?

Interestingly enough, I had a big fear of dogs. I don't really know why because I've never had a traumatic experience with them (thank God I never got bitten).

I also feared being alone, darkness (but not much) and heights. Woah, I was a fearful kid.

Today, well, I only fear those big, aggressive dogs like kangals and rottweilers. As for darkness and loneliness, nah.
