For example, her famous prophecy about the sinking of Kursk, when everybody expected some kind of flood in Kursk town, Russia, while it actually referred to the submarine Kursk which sank in 2000.
Even her own story sounds symbolic to me: she became a seer after she actually lost her sight in a tornado which lifted her up and threw away to the fields. It reminds me a little bit of Dorothy's story from the Wizard of Oz.
Her name is also symbolic: Vangelia means a 'messenger'.
The only Vanga's prophecy which I personally remember reading somewhere in 1990s was her famous: 'Everything will melt like ice, but one: Vladimir’s glory, the glory of Russia'. Nobody heard anything about Putin back then, we had Boris Yeltsin as our President.
And I vividly remember when on December 31, 1999 Yeltsin declared his early resignation and replacement by Putin, my father said: 'OMG, now we've got another Stalin, he is from KGB'. I thought: 'No, this must be the man baba Vanga was talking about'. I still believe that she was right about him as being an outstanding person.
By the way, the name Putin also sounds quite symbolic to me: it is derived from the Russian word Put' which means the Way. So the name can be interpreted as the Leader (he who leads the way).
