Not quite. Zombies are the result of a bocor’s curse or ritual (voodoo black magic). They are real, to a point. They were drugged and had some psychosomatic responses to the curse. I think they’re originally from Haiti, I think, but trace their roots back to the Yourba religions.

They later got picked up by fiction and then turned into mainly biological causes instead of curses.

In “Cast A Deadly Spell” they’re animated by voodoo and are servants. “You can get’em in 6-packs, like bonbons!”
