I don't like coming home to a dark house. I don't like going into the yard when it's dark. I don't like walking the dog when it's dark.
When it's time to go to sleep, there's no way the house will be completely without light. Nightlights are posted in strategic areas like by the kitchen counter, the hallway, the bedroom, even the room where the dog sleeps because Rascal's afraid of the dark also. Why she's afraid is another story which I'll share elsewhere.
For some reason light has magical powers of reducing fear.
I know I'm not the only one who's afraid of the dark. Other mystery authors also know that. It's not surprising that many scary scenes are played out on a dark landscape. Also, the reverse can be true. Witnessing evil in broad daylight can have a chilling effect, since it's so unexpected.
What about you? Are you afraid of the dark? I wonder how many of you use nightlights?
I've put up a quiz here for you to 'fess up.
Also, please leave a comment about what works better for you in your mystery or someone else's - a scary scene played out in the dark or in the light.
