I really don't understand what's behind those types of irrational fears. Some nights I can't even walk from the kitchen to the bathroom without turning the light on in the corridor. I know there's nothing behind the corner, just like I'm sure you knew there were no "terrible things in the night coming to get you", yet I must turn on the light
When I was a kid, I used to think that adults are not afraid of the dark because they are adults. I'm almost 30 now, and I often wonder if I never really became an adult that's never afraid of the dark.
