If you crave advice on sculpting the perfect mustache, revel in the dark and mysterious world of vampires or seek a divorce from your partner, yes, there's a social network for that. Here are 10 weird and truly niche social networking sites that strive to bring together some unusual birds of a feather.
Match a Dream is a haven for people who want to discuss their nightly dreams, decipher their meanings and discover others who share similar ones. You can search a growing database based on the type of dream (scary, happy, sexy, sad, weird), whether it's a recurring dream and the time period in which another user posted a similar dream. Another feature is the "dream circle"—a group of friends you invite with whom you can monitor your dreams and theirs.
