Dear Spy,
JUst "Go with it". Your mind needs to heal. That is why you are having the dream. When you are healed, you will not have the dream anymore.
It seems to be a dream about betrayal , about you looking from the outside on people being happy, and about you giving and getting nothing. A house ,in a dream, represents our self. They have taken over you and are living well, while you are an outsider.This must be how you feel about your life. It is not your own. Other people take it from you and you are on the outside,while they are happy and living well-- right in front of you.
Healing is really scary. I am facing truths ,now. also. It is really, really scary,but it will be better after you grieve them Love Ami
