A number of beliefs and stories about fairies have been popular for hundreds of years. For example, many children believe that the sandman comes each night and puts “sleepy dust” in their eyes to help them sleep. American children especially like the tooth fairy. After losing a baby tooth, a child puts it under a pillow or in a glass of water. During the night, while the child is asleep, the tooth fairy takes the tooth and leaves money. The bogeyman , an evil fairy, kidnaps boys and girls who leave home without permission. The bogey beast, also called the bug-a-boo, carries off children who have been naughty.
