Interesting and informative thread, Nik. Thank you for sharing.
My Sun is in the 7th House . I don't really like it, but it is true that I spend a lot of time focusing on relationships. Not just my romantic ones (although, I do think an awful lot about my romantic relationships). However, I also enjoy relationships in general. I love reading books on psychology, people profiling, astrology..anything that will help me better understand how people think and feel and how these factors influence their interactions with others.
I also enjoy animal to human relationships(how dogs bond with people, with other dogs, other species, ect). Basically, if its relationship oriented, I will probably interested. I am not sure if I would say I am popular, though. I am definitely able to draw people in. Even during times when I am not outwardly inviting. However, I enjoy observing(more than interaction) and learning about relationships from reading the opinion of people who I deem as "experts." I am able to "make friends" just about wherever I go, but I very rarely follow up on them.
My Moon is in the 9th House. and its interesting that you mention that for those with their moon in the 9th House "Practical knowledge is often obtained through dreams or meditation." I think a lot of my knowledge come from real life experience but when I have a very important question and I cannot find the answer in my waking life, I turn to my dreams. It doesn't matter if the question is predictive; "how x feels about me;" or just advice on how to handle a situation, the answers I get are usually really good.
