I used to believe…
...that aliens could see the 'whites of my eyes' through the window in my bedroom at night, unless the light was on. So, I would squint, so that I could see where I was going, if I had to get up in the dark, I didn't want the light from the moon and the stars outside reflecting off my eyeballs and giving away my location. I still don't like it if the blinds or curtains don't completely obscure or block all lines of sight to the outside.
