I realize this was all months ago, but I feel like I have my two-cents worth to add here. I don't think there is any actual connection between the "home" of self and the house you life in, if I'm understanding your premise correctly. Yes, if you have a healthy, balanced sense of self then you are going to be happier. You will be happier in your house. But you would also be happier in a box, with a fox, or out watching the Red Sox. A proper sense of self is going to lead you to be happier wherever you are, the fact that you're happy at home is just coincidental. That being said, the bit where you mentioned "safe" threw up a red flag. No matter how healthy your self image, it doesn't keep you safe "at home in the real world." There are still lots of other "self"s running around out there, and some of them are real loonies.
