I suppose one could use the water houses as a case study :
I have aries on the 4th - i have no planets here but i do have my south node here. (taurus sign)
I have leo on the 8th - no planets here.
I have sagittarius on the 12th - Jupiter here.
Fire signs but i don't necessarily come across like that in this lifetime at least in a obvious manner. How my fire signs do plays out is in ideas. I like coming up with things. I suppose the fire signs in water houses also makes me a quenched fire energy on the surface. On the other hand my fire in water houses expresses itself like a underwater volcano, esp in the realm of relationships where i take my time before sprouting fire, of course there are times when my volcano is dominantly active so that's that.
