The bus shuddered violently as it descended through the portal, surrounded by a cacophony of warped, otherworldly sounds.
The students inside were all unconscious, slumped in their seats, oblivious to the danger rapidly closing in around them.
The portal's swirling lights cast an eerie glow over their still forms.
The vehicle plummeted, weightless, toward an unknown destination, its frame groaning under the pressure.
Finally, the bus burst out of the portal, emerging into a vast, dark expanse.
Below was a churning, pitch-black sea, its waves crashing together like the teeth of a hungry beast.
With a deafening roar, the bus slammed into the water, creating a massive splash that sent waves rolling in all directions.
For a moment, it bobbed on the surface, groaning like a dying whale. Then, it began to sink.
The students were jolted awake by the sudden impact.
