Light from the Past
There is in interesting pheomenon that can happen at night, just before sleep, when you close your eyes. You may be treated to a kind of behind-your-eyes light show, with patterns and colors. I've had this happen to me on and off for many years. But lately I find my brain making actual pictures out of what it 'sees' there. It's like looking at the patterns in marble, where you see a definite outline of something that shifts, suddenly, and then disappears if you move your gaze or turn your head. You might not find it again. Sometimes if I've had a particularly busy day, or used my eyes for more screen time than is healthy, the effect of this light show can be quite detailed. Maybe it's a brain that's aging, sorting through other remembered scenes, and projecting what it finds for my entertainment or attention. The first time I saw actual pictures of people, or vivid cartoon characters, I told myself I had better cut down on the chocolate, or the wine, or the combination thereof.
