Replacing the offhand slot of a zombie villager with a totem of undying and simultaneously affecting the zombie villager with Resistance causes a totem to appear in your head when you look north. I don't know if the same happens with normal zombies. To reproduce: 

1. Create a world in Creative mode.
2. Open your world, get a repeating command block, place it and type /replaceitem entity @e[type=zombie_villager] slot.weapon.offhand 0 totem
3. Place another repeating command block and type /effect @e[type=zombie_villager] resistance
4. Power the command block.
5. Place a zombie villager and
6. Look north.
