A Mental condition
Different people suffer to different degree. For some people with arachnophobia,it is just a mild conditions. Other will yell and scream if they see a spider or spider web. They might become very anxious or start sweating. Their heart might start to speed up or they might have trouble breathing. A person who suffers from arachnophobia might avoid going near dark corners. They might even avoid reaching underneath their kitchen sink to grab a bottle of detergent. They do this because they fear that a spider is living there and will attack them. People who suffer badly from arachnophobia cannot enter a room unless someone else checks it out for spider frist. One woman, called Miss Muffet, was so afraid of spider that she washed her car twice a day. She even used a burning cigarette to scare off the spider.
