Much of nostalgia is an image in our minds. As Boym said, “Modern nostalgia is a mourning for the impossibility of mythical return, for the loss of an 'enchanted world”. Almost a fantasy that we conjure up, whether we believe it to be real or not. But just because the memory may be secured from reality, what can make it feel real is the environment. The environment holds memories even if your nostalgia isn’t about a place.
