There's only one way, and it will take you AGES, but I know it's possible because I've done it!
First, Your going to need one of your sims to master the cooking skill. This can be any young adult sim or older in your household, including the ghost sim himself.
Once they have mastered cooking, take them to the bookstore to by the recipe for 'Ambrosia', it's about 12,000 simeleons, so be ready! Ambrosia is a food that brings the dead back to life, and also can make your sim young again. (they can not "age-down", like turn from a Young Adult into a teenager, but it sets their life span back to the beginning of young adult.) Have your sim read the recipe.
Now believe it or not, that was the easy part! You now have to obtain the two Ambrosia ingredients, The deathfish and Life fruit.
Lets do the deathfish first, and save the hardest til' last. Deathfish always live in the pond in the graveyard, and only come out after 1am, until about 5 or 6am? They are the huge fish shadow. Now deathfish are really rare and hard to catch, so you'll have to have a fishing skill of at least seven, but the higher the skill the more likely you'll catch one. Angelfish is the bait for the deathfish, so it will be alot easier if you buy a few first.
Once you have obtained the death fish it's time to try for the life fruit. And I warn you, this is really hard!! You're going to need the collection helper lifetime happiness reward, it will be next to impossible without it! Set your collection helper to seeds and pick up every 'special' seed you can find. Don't bother with any other types, the life fruit seeds are always special! Now you'll need a gardening skill of at least 7. (I know, I know!!) Plant all your seeds and pray one will turn into a life fruit bush.
Now wait til' there is the 'Harvest' option on the bush. Put both the ingredients in your inventory or fridge then make the Ambrosia. Have your ghost sim eat it.
I really hope this helped, because it took me hours!! I'm a slow typer. :)
Make a ghost scare it
not in the basegame, but if you have late night you have to make the sim a vampire, and make him/her die of thirst (which is hunger for normal sims)
To become a ghost on sims 3 ds: 1. Kill your sim anyway you want to but make sure there is another sim that still lives in that house 2. when your sim dies make the other sim pick up your grave and go to the science lab. 3. when you arrive at the science lab, do the " oh, my ghost! " experiment. 4. Give them the grave and they will resurrect your sim that will now be a playable ghost!
When a sim dies from fire their ghost is red.
The alien sim can't get pregant. But it can make human sims pregant, even boys, or children! But sorry an alien sim can not get pregant!
Make a FEMALE sim that steals things. Make the sims steal mens Graves. WooHoo with the ghots until you have a ghost baby. :)
You have to kill a sim, or moove into a house where there is a gravestone. And make sure no one liked this sim so that the sim gets mad and haunts the family. If you want to get rid of the ghost, sell the tombstone in buy mode. =]
One of your sims has to die. After the sim dies, the Grim Reaper shows up and takes the sim with him. He leaves behind a tombstone or urn (depending on how the sim died). If you don't delete the tombstone or urn, then once in a while the sim's ghost will wander around the lot. It will only be on the lot where the sim died. You can't control the ghost, and it will scare people.
Yes you can make yourself a sim in the sims 2.
no, there is no murdering in the Sims
I think so, just let the sim go hungry and let it die and it should become a ghost.
You can not make a Sim anorexic.
