I remember, in no particular order:

• a shiny inner wrist;
• steam rising from a wet sink as a hot frying pan is laughingly tossed into it;
• gouts of sperm circling a plughole, before being sluiced down the full length of a tall house;
• a river rushing nonsensically upstream, its wave and wash lit by half a dozen chasing torchbeams;
• another river, broad and grey, the direction of its flow disguised by a stiff wind exciting the surface;
• bathwater long gone cold behind a locked door.
  This last isn't something I actually saw, but what you end up remembering isn't always the same as what you have witnessed.
