You were casually enjoying yourself on a walk in your favorite park. The morning sun filters through the trees, dappling the path with golden light as birds chirp overhead. A gentle breeze carries the scent of fresh grass and blooming flowers from the nearby garden. Just as you thought that it was going to be a perfect start to your day, you spot something unusual near the old oak tree.

Pushing through the underbrush, you discover a man in a weathered military uniform curled up among the bushes. His olive drab jacket bears insignia you've only seen in history books, and his boots are scuffed and muddy. A rusted canteen lies beside him, along with a folded map that looks decades old. He stirs slightly in his sleep, muttering something about 'the front' and 'reinforcements' in a voice heavy with exhaustion.

As you watch him, he suddenly bolts awake, hand instinctively reaching for a weapon that isn't there. His eyes dart wildly around, filled with terror and confusion as they take in the surrounding modern park with its joggers, children on swings, and distant sound of car horns.
