1. I rarely play with dogs so idk if this applies to them as well, but in the Sims 2 the ghosts of cats will have translucent heads and bodies, but their eyes, teeth, and tongue will be slightly less transparent.

My sims have a ghost cat, and the amount of guests that have peed themselves after seeing him is hilarious. Even better, my actual household has never seen the ghost.
2. The screams of Sims 1 sims when they burn.
3. The bayou in the Urbz for GBA always unsettled me at night. And Lloyd. He always freaked me out.
