I believe you need their gravestone to get their ghost, not sure if there is a way to find it. There are ways to bring ghosts back to life but believe the gravestone is needed. Can probably get more info online or from others on the forum. I love playing Paranormal so recommend you do try it. The seance table doesn't work, though, to call specific ghosts that are in your game. That would be so cool, though! I enjoy the gameplay and recommend you check out gameplay videos of Paranormal if want to see how it works gameplay wise. The seance table has cool animations and up to 4 sims can participate. If your sim uses it, they can level up in medium ability and obtain the paranormal investigator license and do gigs outside of their home as a job. The table also allows the user to check how haunted the place is, commune with departed, perform a ceremony calm the spirits, invoke the dead which is a random ghost, summon Bonehilda, do a ritual that turn your medium into a ghost temporarily and summon Guidry, who is a guide.. Some of the interactions require a specific medium level. It is a lot of fun!
