Is when your scared of spiders
I have a arachnaphobia of spiders
Arachnophobia is the irrational fear of spiders and other arachnids that will cause Jonathan to scream, cry, have emotional outbursts, experience trouble breathing, sweat, have heart palpitations, or even faint when he comes into contact with spiders, or finds himself in an area near spiders or their webs.
When the spider surprised Jonathan at his desk, his extreme Arachnaphobia caused him to soil his undergarments.
