Science collaborating with the Supernatural!

I think the astrology/horoscope concept could fit in very well too. We could have some astronomical elements which belong to science, so that astrology could collaborate with it. Maybe we will have a whole new set of Sim Zodiacs (not the 12 traditional ones) and we can see the constellations in the backdrop!

Apart from that, the moon phases could be brought into the game, and the full moon could have some effects on Sims' behavior. Gypsy Matchmaker should make a comeback too, and she will probably enable a whole new connection to the dimension of the dead Sims!
