What are you afraid of? Why?

I'm afraid of spiders.Since i was a child,i was terrified of spiders.I would scream and cry if a spider was in my room until one of my parents would come and remove the invader.I'm afraid because they look so ugly and i saw movies that show spiders injecting venom.Now i know that all the spiders aren't dangerous but I'm still afraid of it.I read that ''Arachnophobia'' is the fear of spiders.
