I think its very human to go through that kind of loss, what you describe as a loss of nostalgic feeling. I think it's a part of growing up. You have some sort of expectation of a comforting feeling, tranquility, that just isn't coming. You're blaming your mind, or your experience with DP/DR, but perhaps... it just is what it is.
Nostalgia is not an emotion. You're trying to "feel" back into your past, and something's missing. Your brain is now telling you, "so what, it's a house like a million other houses, what do I care, " right? I wouldn't worry about it. Just move on and look forward, and try to locate your feelings in the present, in whatever you are experiencing right now.
Congratulations on your recovery, that's fantastic.
