The eyelid does not completely hold back the light and lets through some of it. Then it falls on the capillaries and light-catching segments. In the capillaries, the blood moves in impulses, and these impulses are perceived by the eye as flashes of light (with open eyes and due diligence, you can also distinguish a dark "tail" in flashes). This is called the Shearer Phenomenon. In the video, it is detailed from 1:49.

For about the same reason, if you smoke a lot of grass, the visuals will start and are quite bright.
