Well, here's another link, this time it is a list of creepy things.

Though one correction to make is about mummy's curse: the thing appearing on the screen when sim is close to death is not a skull, it's mummy's face. That is much more scarier in my opinion as mummy's face is already scary enough (don't you get creeped out too when you stare closely at a mummy's face?).
And the clown box thing is under The Sims 3, which should actually go under The Sims 2 mainly due to the grouchy personality and memory part.
Though there is one thing I'm wondering: does a creepy music really play when a prank call happens? Some say it does. If you have answers, please share, because right now in my experience the answer is no. Well, it may be because I play with music off due to these danger themes.
