OH I wish there was a way to create a tombstone once they are summoned because them you could create a graveyard in the game with actual tombstones with ghosts in them.

Actually, there is a kill cheat script mod on here for Sims 4. What you could do if you want to create a grave yard is cheat code "sims.spawn" (without quotes, obviously), where a new sim will automatically add to your family (remember that testingcheats does have to be on...), then you use the kill cheat to kill them. Grave stone will appear. Sadly, the cheat script will automatically make them die of starvation, but I mean, if you really want a graveyard, you can't be too picky...
Here's the link for his kill script. It does say that it may not work, but it works perfectly for me, and I have the latest update... :

You are a real life super hero for creating the mod.

Can't get it to work. Sorry. type in summon_ghosts and nothing.

It worked perfectly! Just found out I have a total of 93 ghosts in my town!! It's gonna take a few minutes to get rid of all of them...

*If it's not working, just follow the instructions and add the .zip file to .../Mods, extract nothing! =)

Can you please make a mod where you can summon each ghost individually? It will make for good storytelling.

Thanks for the mod, it works! My sim died and she didn't spawn for 4 sim weeks. Thanks to your mod, I added her to the family again.
Tho... I have 77 ghosts on my lot now....

OH MY GOODNESS! THANK YOU! I created an account just so I could thank you for this mod. I am playing an immortal sim legacy. I am now on generation ~15 and all the ghosts in the game were bogging down my game. I have been searching for something like this for ages! When I loaded up your mod, I had over 200 ghosts! I created a single sim and have been working my way through them, deleting them. I am now at 81... Hopefully this will fix the lag and crashes I keep having. At least it will clear up my immortal sim's relationship panel. Thank you so much!

Hi everyone!! And btw thank you for uploading this mod!! But can anyone tell me a mod to delete sim/ghosts on the game? :D

I'm playing a vampire right now and she needs to be reunited with her long-lost love before he disappears!

Hey i was just wondering if there was a resurrection mod out there so that i dont have to mess around with ambrosia and the book of life. and thanks for this mod it helps me delete ghosts and summon them much more easiliy

YASSSSSSSSSS!!!

Thank for this You're a life Saver I killed my sim by mistake

I'm not sure if I'm doing something wrong but it won't work for me. Any ideas?

Hi- I just DL this and it does work, sort of... It lists 22 sim and pet ghosts - but only some of them actually materialize. fortunately, I was able to capture Old Keanu Reeves {that's his name. he was always old in my game} and reunite him with his wife, Chobani Chang and Keanu Jr. But the ghost of Sucha Dickory never did show up, those his name appeared in the list. :-( Tried it loads of times at different places.

are you going to update this for Seasons? I checked for sumbumbo's mod and found it outdated and he stated he had no plans to update it. He gave a link to someone else who was updating it, but their last update was 2017 some time, so this is my only bet I think.

This mod was perfect for what I needed!! I summoned the ghosts in town onto my lot, found the ghost I was looking for, and implemented the add to family cheat. (Then made him eat Ambrosia to bring him back to life. This townie wasn't supposed to die! He was my sim's adopted grandpa!! He taught her how to fish when she was just a little kid!!)
Thank you so much for this cheat! It worked like a charm!
