Every political border in itself is a memory (reminiscence) of the past, and every redefinition or change of the border involves the past – among other things, borders are also the "physical record" of the history of states. Phantom borders and actual political borders may correspond to each other, or, in other words: modern borders also contain the phantom borders. Political borders may outlive the existence of the states that created them. Many such examples exist in the Central and South-East Europe, and the Slovenian-Croatian border definitely belongs to this category. If we dare develop the phantom border metaphor further, we can ascertain that the modern political borders have a "body" (border crossings, fences, markings), which can become possessed by the historical phantom. How shall we refer to this phenomenon? The expression "zombie border" does not quite fit, because modern borders have a living "body" which is merely possessed by the historical spirit. Could we simply call the phenomenon "a possessed border"?
