This reminds me, I forgot the dream I had this morning ):

My dream from the day before involved a pigeon who flew into my house and I tried to chase him out. And then my budgie started attacking him...

Independent I would becareful exploring the websites which have little relations to science and many relations to telepathy, magic and witchcraft. On many occasions they tend to be very wrong and just out to scam people...

I was very surprised to see you put so much relevance onto stationary objects in your dream and so little relevance to people and your relations with them. There are a lot of feelings and emotions coming out of this dream. Your subconscious is screaming at you. I am in no way certified in dream analyses, but certain things really hit me in the face. E.g. Your strong subconscious dependence on your BF i.e. him being in charge of your immediate surroundings, your need to communicate with him, your need for a sense of closure. I think there maybe some emotional dependency issues to consider...

Other suggestions, loose teeth tie in with insecurity or lack of confidence in your abilities. Mansion can also stand for a facade to cover or put a nice face onto issues floating beneath the surface...

My Demon revokes any prayer
He's grown contempt for love and hope
He betrays trust, twists truth and fair
Indifference is his way to cope
Engulfing sound of sensations
He quells with voices of despair
And muse of short lived inspirations
Flees at the sight of his cold stare
