Use your imagination to think up ''some kind of body-guard unit'' surrounding you.

I know it worked for me, as what's in the dark, is not "REAL" like humans are, they should be from some kinda other world.

So I just imagine (even if I can't REALLY see them, like a hologram of sorts) a special unit that covers my back and front and stuff, and just imagine as if evil is already coming, and they're just slaying it.

Either that, or I just act like i'm talking to myself or to someone else in a natural way about stuff, and it keeps my mind off it as well.

3rd: My room is considered a save haven of magic for me, so nothing can penetrate there so I don't care if that room is totally dark
