Controlling Ghost Sims in The Sims 3 (Xbox 360): Not Directly Possible

You cannot directly control a ghost Sim in the Xbox 360 version of The Sims 3. Ghosts run on autonomous AI.

What You Can Do

• Interact socially — Chat, scare, flirt (if traits allow).
• Use cheats — testingcheatsenabled true → Shift-click ghost → "Trigger Age Transition" (resurrect) or "Add to Household" (playable).
• Place "Tombstone of L and D" (buydebug) — Gives ghosts specific haunting goals.

Console Limitation

The Xbox 360 version lacks Create-a-Ghost and ghost color/customization features present in the PC version (via patches/mods).

If you want full ghost control, the PC version with mods (NRaas MasterController) is the only way.
