The Most Common is Somniloquy

There are a lot of common sleeping disorders that people know about from experience; like tossing and inability to fall asleep. Some of the strangest for me are sudden jerks and muscle reactions towards dreams. However everyone has heard about somniloquy or better known as sleep-talking. If you haven't witnessed it yourself you might not recognize it. Most of the time the speech is low enough that you can't make out what the other person is saying. Most sleep-talkers are either children or teens. There are a small percentage of adults that do talk in their sleep with very loud and clear speech but it is quite rare.
