You were thirsty. So I said I will meet you in a dream and pour you a glass of sparkling pink lemonade over dry ice. As it sublimates a shroud of frothy mist will form and travel past the brim into the air between us.
And you will trace silvery incantations onto the glass with your fingertip. The mist will linger, but then it will thin, eventually it will evaporate so all that is left at the bottom of the cup is a shallow pool of sparkling lemonade. Your etchings, dissolved.
At this point in the dream, I will leave for a few years. When I come back the cup will still be in the same place you left it and I will breathe close to it the fog of my breath will cling to the glass and like a ghost it will reappear: All that disappeared; All that you wrote, years ago.
Then I will wake up and forget this dream. Years are only seconds combined. The evidence will remain, my tongue quaking from the burn of dry ice. My head wavering with confusion, as though what it contains is not opaque, but foggy, pink and citrus. From this point on, I can't say what will happen to you.
