Waterfall
It sure got brighter all of a sudden. You can just keep yourself from falling into the raging waters that flow down a turbulent waterfall. Carefully looking down you see that the water pools at the bottom, but the cliff wall is too steep to scale. Thinking you'd better head back you suddenly feel the cold embrace of a snake winding it's way around your neck. You just manage to whisper: "Fiddlesticks". before you black out.

Better luck next time!
