How can you wake up dead?

This is what buggs me. When people say "Oh, we don't know much except that he woke up dead this morning."
Here is my question: How can you 'wake up' dead if you're already dead and can't wake up. This is what irritates me alot. Oh and um to the Altona People out there, what is going to be happening on Friday? Is there going to be a barbacue or what? l8er
