As a kid I used to crave wanting to eliminate all light when I went to bed. As a teen, I would seal the edges of my door to stop the hall light in our house from coming and put up black out curtains even at night. It always bothered me if I woke up with a bit of light. For some reason I felt better waking up in the dark. I always know where my things are and I can wander around in the dark to f find my way.
I haven't had that in years because my wife wants some night lights on somewhere. She thought I was nuts to want complete darkness at night.
Yeah I'm not as unafraid of the dark as you'd expect. I like being in the complete darkness in the comfort of my own space that I know very well .... like my bedroom or my living room or any room in my house that I know very well. But when it comes to being in the dark in a strange and unfamiliar place .... yeah, I'm not comfortable and I would also start seeing figures and faces too.
