Stare at the four black dots in the center of the image for 30 - 60 seconds. Then quickly close your eyes and look at something bright (like a lamp 또는 a window with sunlight coming through it). 당신 should see a white 원, 동그라미 with an image inside it.
당신 don't nessasarily need to watch this all the way though but on pause it at 4:46 a floating shadow can be seen 5:09 a man/figure can be clearly seen when the camera goes back a mere 초 later the man/firgure is gone
