You bolt awake in a cold, moving place.  Your eyes sting a little so you wipe them with one hand and open them while trying to stay afloat in the fast water.  You can still barely see anything in this dark; you must be underground or something; it’s probably all a dream.  But the drain!  Could you have fallen through the drain?  You nearly go under while using one hand to pinch yourself in a few places to make sure you’re not dreaming.  The pinches don’t hurt but you know you’re not dreaming; you’re just numb from the cold water.  After you’ve been treading water for what must be hours, you find a shallow patch with your foot and climb up, digging in-between the rocks with your numb fingers to fight the current.  After a hard battle, you get yourself up onto a smooth ledge out of the water and lay there panting in the cold darkness.  How in the world did it come to this?  Not daring to go back into the water, you sit and wait for rescue.  With your phone destroyed and no clear idea of where you are, it could be a long wait.  Maybe you’ll float further down the river tomorrow, but for now, you’re free.  And wet.
