Is there a way to bring back a Sims ghost to their grave

@WonkyCats Here is some good information on ghosts. I'm not sure if you want the ghost back in the game for play, if they are already sent to the netherworld, or do you mean that you want them back in to the grave and send to the netherworld (this one is in this article: http://www.carls-sims-4-guide.com/death/ghosts.php ...plus more information is this one, though I'm not sure it is what you are looking for: https://simsvip.com/2014/10/06/sims-4-ghost-guide/  .) Can you perhaps clarify what your desire is for bringing them to the grave, where the grave is, (at home, etc.), if you were seeing them before and where, your last interactions with... whatever may seem relevant to this sim and the ghost. Thanks!

So, I had a character I was playing but then o stopped moved them out cause she became grandma, she died. Her ghost moved on to the Netherworld, BUT I managed to get her urn! So I am hoping there's a way to bring her ghost back so I can then bring her back to life. So that great grandma is alive!!! Can it be done?

@WonkyCats I play with aging off (I'm such a wimp) but all that I am finding on this seems to indicate that once they are released to the netherworld they are gone from the game, apparently. Here is a posting/article about this aspect. https://www.quora.com/On-the-Sims-4-is-there-a-way-to-bring-ghosts-back-from-the-netherworld-Not-too-long-ago-I-released-a-family-member-to-the-netherworld-but-Im-wondering-if-there-is-a-cheat-or-something-that-would-work  If I find out anything different I will post additional information. Sorry to not have better news about grams! ☹️

Thanks for your help I knew it was a long shot.
