Very rarely when my eyes are closed in the dark I'll see bright white flashes- For a while I just assumed it was Brain Weirdness, but then I remembered how astronauts report that happening a lot, and now I wonder if it's random cosmic ray events
@VoxSomniator Do you live at a high altitude?
@Rosemary Not especially
@VoxSomniator i bet astronaut brains are pretty weird too
