Look for a young woman and an old woman in this picture. Do you see both? Can you see both at the same time? Is your mind projecting an image and identity (with age features) onto this collection of lines?
One woman is looking away from you, one is looking down. What does that evoke? Does she remind you of anyone you know?
When you see someone at a distance you think you know, walking toward you, you see her face. But as she gets closer, the face may change into someone else. You saw a familiar face on her before, because your brain’s theatre projected it.
