I used to believe that the Sandman (and his wife and kids, the whole family) lived in my closet. They were invisible, of course. My father would tell us stories about them at bedtime, and we'd leave the closet door cracked open just a teeny bit so that the Sand People could get out and wander around the world putting sleep-sand in people's eyes to make them sleep. And you know, when we woke up, there was usually a little bit of "sand" in the corner of one or both of our eyes!
