Occult activities such as casting spells and using vampire powers (unless that is actually in the game if you have the corresponding packs, then this point is moot.) Maybe you have a vampire who really, really dislikes being a vampire, and gets sad or angry when using his powers. Or maybe you have a witch who loves magic so much that she uses it for everything, and gets frustrated when she has to mop up a puddle the old-fashioned way.
If it's not limited to activities, then occults themselves could be on the list, too. I always found it strange that there's no way of making sims afraid of or totally into, say, aliens. Every sim basically reacts the same to occults doing their thing around them. Likes and dislikes could solve that.
