Supernatural Sims in the Afterlife?

So.. THIS happened. Unexpectedly. 

Last night I made a new sim so that I could create a new vampire... I only became one last night and barely got a chance to play as a vamp. Instead, I took him to the library to research vamp stuff and then out to get some frogs. Apparently within a couple sim hours, he burned to death. As he laid on the ground dying, I panicked and quickly used the testing cheat to make him all happy.. then grim asks me if I want him to be a playable ghost, so I clicked yes. And then returned him to his home... he just got a job and I guess it's business as usual. I don't have the new EP because it hasn't been released yet. However, I still have vampire powers as a ghost. So in case anyone else was wondering... this was a complete mistake but I got the answer to my question.
