You can also use a cheat to turn a sim into a playable ghost.
You will need to turn on testingcheats on before entering the ghost trait.
CHEAT TO GET A GHOST http://www.carls-sims-4-guide.com/death/ghosts.php
The following cheats add or remove a specific type of death trait that is responsible for making a Sim into a ghost in the first place. Turning one of these on will immediately turn them into a ghost of the appropriate type. Equip the trait with traits.equip_trait X to turn them into a ghost or remove it with traits.remove_trait X to return the Sim back into a normal, living Sim. For this second part, you must use the exact type of death cheat to reverse it. Use the simology panel (hotkey Y) if you're unsure.
traits.equip_trait anger - Anger, and for example traits.remove_trait anger to remove it. This cheat may be temporarily broken due to a patch.
traits.equip_trait cowplant - Cow Plant
traits.equip_trait drown - Drowning
traits.equip_trait electrocution - Electrocution
traits.equip_trait embarrassment - Embarrassment
traits.equip_trait fire - Fire This cheat may be temporarily broken due to a patch
traits.equip_trait hunger - Hunger
traits.equip_trait laugh - Laughter
traits.equip_trait oldage - Old Age
traits.equip_trait exhaust - Overexertion (Old Age)
traits.equip_trait steam - Sauna
Specifically, it's traits.equip_trait trait_ghost_x
Just typing 'traits.equip_trait x' works right now because no other traits have names that are close. Once there is ambiguity, this may stop working.

It is great.

^I want that one.
I would like to see a Sim suddenly start inflating and then just explode - like an over inflated balloon.
Just imagine the look on any nearby Sims - as they peel the exploded Sim from their faces.
