[Folklore] Can a zombie and a ghost come from the same person?

If the ghost possesses the zombie, does the person come back to life?

Yes, both can come from the same person.  The zombie is the reanimated corpse of the person, nothing more.  The ghost is the person themselves, in spirit or spectral form.  
Possessing the zombie might allow for some communication with the living, but it would be no more actual life than the zombie itself is.
