Had the same feeling again today, i went for a walk and went to another shopping centre. This time i could see in there, but it was just empty, a big empty building. Still has HMV over the door way so for a second i was like "when did it come back?" (since i knew it shut down a while ago). As i walked on by, all the memories came flooding back again, and i could picture where everything once was. So "weird" but fascinating to me at the same time. But as years gone by, shops have come and gone in that area, so as i walked round that feeling kept coming back.
