There are probably times when you've been accused of talking in your sleep. It's not just humans that are guilty of this, however. Cats are also guilty of doing things in their sleep. My cat, for example, will meow in her sleep, right after she's done snoring and she's stunk up the room with her rancid gas. The cat in the video below is a feline who is also guilty of talking in his sleep. Sure, the sound has been added, but I still find it funny. Then, when you least expect it, this video will pop into your mind and you'll find yourself muttering to your friends. They'll have no idea what you're talking about.
