there is no frankinstein in the sims2, but there is zombies. one of my sims fear was "vamsi(the dead sim) becomes a zombie"
and under the description was "stay away from a sim who has a resurecto-tron(can be bought after getting to the top of the paranormal career) or whatever its called
using debugging mode zombie skin is availible as well.

Is that only because you have Nightlife? Because I never get that Want and I don't have Nightlife yet and I've been playing Sims 2 for ages.
