Usually using the bathroom in a dream is asking you to eliminate something and money is about heart and feelings. This part 2 is bringing up childhood conditioning (pattern embedded) which has actually affected your heart (living room) to the point that you are physically affected (lining of wallpaper is about the lining of your heart). Eating dairy when you shouldn't (from previous post) can affect your heart but I'm actually wondering if you have a real problem with "using the bathroom too much"? The dream may be suggesting that this, too, is creating an imbalance for your heart health.
