> rewinding it in my head This works for short term audio. Sometimes you hear something without paying attention and you don't understand, but you can somehow replay the sound in your head and parse it again. Maybe a related phenomenon for vision. When you are in the dark in the middle of the room, not knowing where the obstacles are. You flash a light for a very brief, subliminal instant. Your brain can't process the scene during that flash, but you can somehow mentally study and make a mental map of the obstacles later. On the other hand I personally can't produce any meaningful memories of odors.
