Are people afraid of the dark?

I live in a very safe neighborhood. People have about an acre. Crime is low and the area is quiet. We have foxes, hawks and deer.

My neighbors insist on keeping their entire yards lit up all night every night. Garage lights. Shed lights. Path lights. Porch lights. You can walk into the woods at midnight without a flashlight. If I don’t close my blinds, I can see around my bedroom at night and there would be shadows on the floor.

Nobody in the whole neighborhood, except a few of us, time out lights to go off overnight. It got me thinking. Are people afraid of the dark? (Note - I think afraid of crime = afraid of the dark, but with a socially acceptable excuse)
