As the bus entered the tunnel, the atmosphere inside shifted dramatically. The once bright and open surroundings gave way to darkness, enveloping the students in an eerie shroud. The tunnel walls, made of rough concrete, loomed overhead, casting long shadows that danced ominously in the dim light. The air grew noticeably colder, sending a chill down the students' spines as they huddled together for warmth.
The tunnel seemed to stretch on endlessly, its depths swallowed by the darkness that surrounded them. The only sound was the rumble of the bus's engine, echoing off the walls of the tunnel like distant thunder. Occasionally, the screech of metal against metal pierced the silence as the bus navigated its way through the narrow confines of the tunnel.
