unfolding

It looks as though the sheets in the next room's reflection are unfolding. Though it's an illusion (the tarpaulin on the garage opposite flaps cautiously in the wind), they will be unfolding in two days' time. One of the bed's inhabitants will send herself 180 around the world and the sheets will be unfolding with restless single-handed searching -- for something that was never honestly there in the first place, but stayed for a little while and played pretend.
