It’s only just occurred to me that I no longer have to sleep with the lights on.
All through childhood, I needed a light somewhere. If you could see the light, nothing (ghosts, spirits, owls, moths, and demons included) could get you. You didn’t have to be in the light, you just had to see it. Those were the rules.
Now I turn off all the lights before I sleep. Sometimes a streetlight shines in through the bathroom window. Sometimes it’s too bright for me to sleep. I’m still afraid of the dark, though.
